org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host Linux error that works on Windows

I have looked at many (too many) similar questions here and tried over and over to solve this one but I can't quite get it to resolve.
I have a java code that connects to a PostGreSQL server on a RHEL 8.2 box to query and return a value. When I run it on my Windows 10 laptop; it works with no issues. However, when I run it locally on the Linux box it fails with the dreaded org.postgresql.util.PSQLException: FATAL: no pg_hba.conf entry for host.
The java code is made by a ETL software called Talend; and the code is run on Linux by RunDeck.
To make matters more confusing, I can login on Linux as the postgres user and use the psql interface to connect to the db with the same host, port, db, and user I'm using in Java without error-
psql -h [server ip] -p 5432 -d my_special_db -U my_db_user
I have checked the server settings, the pg_hba.conf file, the user permissions, the log files and tried changing all of the above to get some sort of return; all to no avail.
I have added to pg_hba.conf:
host my_special_db my_db_user [server ip]/32 md5
host my_special_db my_db_user [server ip with .0 as the last quatraine]/24 md5
host my_special_db root ::1/128 trust
host all all [server ip]/32 trust
I have tried multiple connection modifiers like:
sslfactory=org.postgresql.ssl.NonValidatingFactory&sslmode=prefer
or
sslmode=prefer
or
sslmode=Require
or
no modifier at all
Please advise.

I have gotten this error even after the following updates-
update to the postgresql.conf file:
edit 1
ssl = off
edit 2
ssl = on
edit 3
#ssl = off
updated the log level in the postgresql.conf file to
log_line_prefix = '[%p] [%c] [%m] [%v] [%e] [%i] [%d] [%u] [%a] [%r] [%l] [%x]: '
...
log_statement = 'all'
updated the pg_hba.conf file to start with:
# Allow any user on the local system to connect to any database with
# any database user name using Unix-domain sockets (the default for local
# connections).
#
# TYPE DATABASE USER ADDRESS METHOD
local all all trust
# The same using local loopback TCP/IP connections.
#
# TYPE DATABASE USER ADDRESS METHOD
host all all 127.0.0.1/32 trust
# The same as the previous line, but using a separate netmask column
#
# TYPE DATABASE USER IP-ADDRESS IP-MASK METHOD
host all all 127.0.0.1 255.255.255.255 trust
# The same over IPv6.
#
# TYPE DATABASE USER ADDRESS METHOD
host all all ::1/128 trust
# The same using a host name (would typically cover both IPv4 and IPv6).
#
# TYPE DATABASE USER ADDRESS METHOD
host all all localhost trust
hostssl all all 0.0.0.0/0 md5
also updated the connection params with-
sslfactory=org.postgresql.ssl.NonValidatingFactory
According to postgres this is supposed to stop any and all SSL issues and just let the connections through-
https://jdbc.postgresql.org/documentation/head/ssl-client.html
"A non-validating connection is established via a custom SSLSocketFactory class that is provided with the driver. Setting the connection URL parameter sslfactory=org.postgresql.ssl.NonValidatingFactory will turn off all SSL validation."
Update 5:
Logging settings from postgresql.conf file:
#------------------------------------------------------------------------------
# REPORTING AND LOGGING
#------------------------------------------------------------------------------
# - Where to Log -
log_destination = 'stderr' # Valid values are combinations of
# stderr, csvlog, syslog, and eventlog,
# depending on platform. csvlog
# requires logging_collector to be on.
# This is used when logging to stderr:
logging_collector = on # Enable capturing of stderr and csvlog
# into log files. Required to be on for
# csvlogs.
# (change requires restart)
# These are only used if logging_collector is on:
log_directory = 'log' # directory where log files are written,
# can be absolute or relative to PGDATA
log_filename = 'postgresql-%a.log' # log file name pattern,
# can include strftime() escapes

I couldn't paste the error log here because after making it verbose it was very long- so I made a gist
Last update:
I removed the Gist because the peeps here helped me find my error:
okay, so the issue was 3 things; thing 1, we have a 'properties' file that I thought was set to this server this db; and it wasn't // thing 2, the default logging was set to 'warning' and didn't have enough information so after putting it to debug level 5 (the most data) and on 'all' events; I finally saw a error message that made me realize it was pointed at the wrong db // thing 3, in the many (too many) iterations of my pg_hba.conf file I had added then removed the IP address.
so now it's working, lol

Cannot connect java mail to postfix smtp server

I'm facing an issue right now. I configure my postfix server together with dovecot and everything works well so far. I could connect some accounts using my phone email client with the parameters:
Host: imap.mydomain.com
email: xxx#mydomain.com
password: xxxxxxxx
port: 993
and
Host: smtp.mydomain.com
email: xxx#mydomain.com
password: xxxxxxxx
port: 465
Accept all SSL certificates
Now I want to connect my java app with the smtp parameters to send emails. Unfortunately, it takes too long and then I get a time out exception.
On the server, I get the following from the logs:

how to configure a email functionality in play-java 2.5.4

I wrote the following code for email functionality:
import org.apache.commons.mail.DefaultAuthenticator;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.HtmlEmail;
import play.mvc.Controller;
import play.mvc.Result;
public class MailController extends Controller {
public Result sendEmail() throws EmailException {
HtmlEmail email = new HtmlEmail();
String authuser = ".......#gmail.com";
String authpwd = "XXXXXXX";
email.setSmtpPort(587);
email.setAuthenticator(new DefaultAuthenticator(authuser, authpwd));
email.setDebug(true);
email.setHostName("smtp.gmail.com");
email.setFrom(".........#gmail.com", "SenderName");
email.setSubject("TestMail");
email.setHtmlMsg("<html><body><h1>welcome to u</h1></body></html>");
//email.addTo(".......#gmail.com", "receiver name");
email.setTLS(true);
email.send();
return play.mvc.Results.ok("Success");
}
}
However, I'm facing problems (such as exceptions getting caught in Netty).
I added a plugin in bulid.sbt:
libraryDependencies ++= Seq(
"com.typesafe.play" %% "play-mailer" % "5.0.0-M1"
)
application.conf:
# Mailer
# ~~~~~
play.mailer {
host=smtpout.secureserver.net
port=587
ssl=false
tls=false
user=my username
password=my password
debug=false
mock=false
}
This is one of the errors that I'm facing:
[error] p.c.s.n.PlayRequestHandler - Exception caught in Netty
java.lang.NoClassDefFoundError: Could not initialize class play.api.http.DefaultHttpErrorHandler$

How can I fix this?
my application.config file is as below
# This is the main configuration file for the application.
# https://www.playframework.com/documentation/latest/ConfigFile
# ~~~~~
# Play uses HOCON as its configuration file format. HOCON has a number
# of advantages over other config formats, but there are two things that
# can be used when modifying settings.
#
# You can include other configuration files in this main application.conf file:
#include "extra-config.conf"
#
# You can declare variables and substitute for them:
#mykey = ${some.value}
#
# And if an environment variable exists when there is no other subsitution, then
# HOCON will fall back to substituting environment variable:

# Play uses Akka internally and exposes Akka Streams and actors in Websockets and
# other streaming HTTP responses.
akka {
# "akka.log-config-on-start" is extraordinarly useful because it log the complete
# configuration at INFO level, including defaults and overrides, so it s worth
# putting at the very top.
#
# Put the following in your conf/logback.xml file:
#
# <logger name="akka.actor" level="INFO" />
#
# And then uncomment this line to debug the configuration.

# Please see https://www.playframework.com/documentation/latest/GlobalSettings
# for more information.
#
# You can also extend Play functionality by using one of the publically available
# Play modules: https://playframework.com/documentation/latest/ModuleDirectory
play.modules {
# By default, Play will load any class called Module that is defined
# in the root package (the "app" directory), or you can define them

## Cache
# https://www.playframework.com/documentation/latest/JavaCache
# https://www.playframework.com/documentation/latest/ScalaCache
# ~~~~~
# Play comes with an integrated cache API that can reduce the operational
# overhead of repeated requests. You must enable this by adding to build.sbt:

## Filters
# https://www.playframework.com/documentation/latest/Filters
# ~~~~~
# There are a number of built-in filters that can be enabled and configured
# to give Play greater security. You must enable this by adding to build.sbt:
#
# libraryDependencies += filters
#
play.filters {
## CORS filter configuration
# https://www.playframework.com/documentation/latest/CorsFilter
# ~~~~~
# CORS is a protocol that allows web applications to make requests from the browser
# across different domains.
# NOTE: You MUST apply the CORS configuration before the CSRF filter, as CSRF has
# dependencies on CORS settings.
cors {
# Filter paths by a whitelist of path prefixes

## CSRF Filter
# https://www.playframework.com/documentation/latest/ScalaCsrf#Applying-a-global-CSRF-filter
# https://www.playframework.com/documentation/latest/JavaCsrf#Applying-a-global-CSRF-filter
# ~~~~~
# Play supports multiple methods for verifying that a request is not a CSRF request.
# The primary mechanism is a CSRF token. This token gets placed either in the query string
# or body of every form submitted, and also gets placed in the users session.
# Play then verifies that both tokens are present and match.
csrf {
# Sets the cookie to be sent only over HTTPS
#cookie.secure = true
# Defaults to CSRFErrorHandler in the root package.
#errorHandler = MyCSRFErrorHandler

## Security headers filter configuration
# https://www.playframework.com/documentation/latest/SecurityHeaders
# ~~~~~
# Defines security headers that prevent XSS attacks.
# If enabled, then all options are set to the below configuration by default:
headers {
# The X-Frame-Options header. If null, the header is not set.
#frameOptions = "DENY"
# The X-XSS-Protection header. If null, the header is not set.
#xssProtection = "1; mode=block"
# The X-Content-Type-Options header. If null, the header is not set.
#contentTypeOptions = "nosniff"
# The X-Permitted-Cross-Domain-Policies header. If null, the header is not set.
#permittedCrossDomainPolicies = "master-only"
# The Content-Security-Policy header. If null, the header is not set.
#contentSecurityPolicy = "default-src 'self'"
}
## Allowed hosts filter configuration
# https://www.playframework.com/documentation/latest/AllowedHostsFilter
# ~~~~~
# Play provides a filter that lets you configure which hosts can access your application.
# This is useful to prevent cache poisoning attacks.
hosts {
# Allow requests to example.com, its subdomains, and localhost:9000.
#allowed = [".example.com", "localhost:9000"]
}
}
## Evolutions
# https://www.playframework.com/documentation/latest/Evolutions
# ~~~~~
# Evolutions allows database scripts to be automatically run on startup in dev mode
# for database migrations. You must enable this by adding to build.sbt:
#
# libraryDependencies += evolutions
#
play.evolutions {
# You can disable evolutions for a specific datasource if necessary
#db.default.enabled = false
}
## Database Connection Pool
# https://www.playframework.com/documentation/latest/SettingsJDBC
# ~~~~~
# Play doesn't require a JDBC database to run, but you can easily enable one.
#
# libraryDependencies += jdbc
#
play.db {
# The combination of these two settings results in "db.default" as the
# default JDBC pool:
#config = "db"
#default = "default"
# Play uses HikariCP as the default connection pool. You can override
# settings by changing the prototype:
prototype {
# Sets a fixed JDBC connection pool size of 50
#hikaricp.minimumIdle = 50
#hikaricp.maximumPoolSize = 50
}
}
## JDBC Datasource
# https://www.playframework.com/documentation/latest/JavaDatabase

com.mysql.jdbc.exceptions.jdbc4.CommunicationsException MySQL + Apache Tomcat 7

My application (Spring 4 MVC / Hibernate 4 / MySQL / Maven) integrates Spring with Hibernate using annotation-based configuration. After a few hours of it not using the database I always see this error:
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 84,510,841 milliseconds ago. The last packet sent successfully to the server was 84,510,841 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

I am using a connection pool defined as follows:
<?xml version="1.0" encoding="UTF-8"?>
<Context>
<!-- Especifica un DataSource JDBC. -->
<Resource name="jdbc/devicesDS"
auth="Container"
type="javax.sql.DataSource"
maxActive="10"
maxIdle="4"
username="root"
password="SrbBfsatn640^"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/devices?autoReconnect=true"
validationQuery="select 1 from dual" />
</Context>

Looks like this is the MySQL inactivity timeout - there's quite a few similar StackOverflow questions around it (e.g. here, here and here). Would advise changing your connection pool settings by adding testOnBorrow=true, i.e:
<Resource name="jdbc/devicesDS"
auth="Container"
type="javax.sql.DataSource"
maxActive="10"
maxIdle="4"
username="root"
password="SrbBfsatn640^"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/devices?autoReconnect=true"
validationQuery="select 1 from dual"
testOnBorrow=true />
I'd personally lean towards testOnBorrow over the alternative of testWhileIdle since the former is completely independent of the wait_timeout value (but not sure how the performance compares). Would also be cautious about using the alternative of autoreconnect=true in the JDBC URL: It isn't recommended by the MySQL Connector/J documentation "because it has side effects related to session state and data consistency when applications don't handle SQLExceptions properly, and is only designed to be used when you are unable to configure your application to handle SQLExceptions resulting from dead and stale connections properly".

In your application the connection string to database mysql should be:
jdbc:mysql://{host}:{port}/{schema}?autoReconnect=true
adding autoReconnect=true will solve this issue

I run onto this problem with other app implementations, after tryed every config, autoreconnect, etc.
The only way I find to solve this was making an schedule event calling a test query every hour to ping the DB, forcing it to refresh the connection.
query("SELECT version()");
