Configuration of AWS with Sequel Pro

I am using Sequel Pro 1.1.2 in MacOS Mojave, when trying to configure the AWS database instance getting error as
" Unable to connect to host vinay-awsdb.cinbpy8tpejb.eu-west-1.rds.amazonaws.com, or the request timed out.
Be sure that the address is correct and that you have the necessary privileges, or try increasing the connection timeout (currently 10 seconds).
MySQL said: Can't connect to MySQL server on 'vinay-awsdb.cinbpy8tpejb.eu-west-1.rds.amazonaws.com' (4)"
In the standard connection mac for Sequel Pro,I am entering the following:
Name: (used my instance name which is vinns, and also tried leaving it with the default of 'optional')
Host:vinay-awsdb.cinbpy8tpejb.eu-west-1.rds.amazonaws.com
Username: (used my master user name)
Password: (used my master users password)
Database: (used database name mydbname, and also tried leaving it with the default of 'optional')
Port:3306
I am not able to connect.
I also tried by changing the Inbound rules to anywhere and increased connection timeout to 60 but did not worked

Can't connect to Sql Server database using JDBC

I'm trying to make a connection to an already existing database in SQL Server 2012n with Netbeans 8.
Using the connection wizard I select Sql Server 2012 and enter the credentials and fields.
However I get the message that a connection cannot be established.
You can see screenshots of the entered fields:
I also tried using "localhost" instead of "STIJN" this didn't work. I also tried with the default port "1433". Also didn't worked, however what port should this be? Where can I see what port I'm using? Maybe the error lies in the port, otherwise I wouldn't know where I made a mistake.

Go to your SQL Server configuration manager -> SQL server network configuration -> protocols for SQLEXPRESS -> TCP/IP (double click on it for properties).
On protocol page set enabled to Yes.
On IP Addresses page, scroll to bottom.
TCP Dynamic Ports: 54629
TCP Port: 1433
Apply and ok.
Make a connection with:
Host: localhost
Port: 1433
Your credentials
Instance field = blank.
This should work.

The TCP/IP connection to the host localhost, port 1433 has failed

I'm getting this 2 errors repeatedly when I'm trying to connect eclipse with sql server through jdbc. Could anyone help me with this or explain why am I getting this?
1. The TCP/IP connection to the host localhost, port 1433 has failed.
2. The driver could not establish a secure connection to SQL Server by using Secure Sockets Layer (SSL) encryption.
Thank you.
String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
Class.forName(driver).newInstance();
String connString ="jdbc:sqlserver://localhost:1433/databaseName=Engg_Street;instance=SQLSERVER;encrypt=true; trustServerCertificate=true";
String username = "Vijayalakshmi";
String password = "";
conn = DriverManager.getConnection(connString,username,password);

You need to Go to Start > Microsoft SQL Server > Configuration Tools > SQL Server Configuration Manager
When it opens Go to
SQL Server Configuration Manager > SQL Server Network Configuration > Protocols for SQLExpress
Where you'll find the Protocol TCP/IP, if disabled then Enable it Click on TCP/IP, You'll find its properties.
In this properties Remove All the TCP Dynamic Ports and Add value of 1433 to all TCP Port
and restart your SQL Server Services > SQL Server
And Its Done...

If you are running SQLSERVER EXPRESS:
Use "SQL Server Configuration Manager" or write "mmc.exe" on Win+R and search "SQL Server Network Configuration", in the "Protocols for SQLEXPRESS" enable the option TCP/IP
I hope than this works for somebody!!

For this kind of issue - you can resolve by checking whether all sql server related services are running or not.
TO check Start -> Run -> services.msc
check services related to sql as
SQL Server (MSSQLSERVER)
SQL Server Agent (MSSQLSERVER)
SQL Server Analysis Services (MSSQLSERVER)
SQL Server Browser
SQL Server Integration Services 10.0
SQL Server Reporting Services (MSSQLSERVER)
SQL Server VSS Writer
Start all the above services. and set to start up type to Automatic.
SQL Active Directory Helper Service is not required to keep running.

or please check if the table name is duplicated, i changed the table name --> problem solved

connecting to postgreSQL server failed

I am trying to install "Kwok information server" and I am new to postgreSQL. I just followed the installation guide of Kwok information server.
when I am trying to install kwok-schema-setup.jar file using java through postgreSQL server in Command Prompt, I am getting the following error..."Connecting to PostgreSQL Server ...failed. Connection refused. Check that the ho
stname and port are correct and that the postmaster is accepting TCP/IP connecti
ons. Cause: java.net.ConnectException: Connection refused: connect
Schema setup encountered errors" .
And when I am trying to connect to the server using pgAdmin III, I am getting the following error "Server doesn't listen
The server doesn't accept connections: the connection library reports
could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432? ".
Please anyone help me regarding, Thanks in advance!!

Looks like your Postgresql daemon is not running. Check if the server has started and is running. I dont know which OS you are using but try ps -ax on linux/mac or the task manager in windows.
Maybe a firewall that is blocking the connection, you have to provide more information about your environment to be sure.

Connection JDBC SQL Server Error

I've tryed to create a connection with a Microsoft SQl Server 2008 database through JDBC on Eclipse SDK. I've dowloaded JDBC driver from microsoft and I've installed it, then I've added at my System environment variables CLASSPATH the path of sqljdbc4.jar file. After icluding in the Eclipse project the jar file I've tryed to create the connection using:
String connectionUrl = "jdbc:sqlserver://localhost;integratedSecurity=true";
Connection con = DriverManager.getConnection(connectionUrl);
but it doesn't works, and launch me this exception:
com.microsoft.sqlserver.jdbc.SQLServerException: TCP/IP connection
at host localhost, port 1433 failed. Error: "Connection refused:
connect. Verify connection properties and make sure an instance of SQL
Server is running on the host and is accepting TCP/IP connections at
the port. Be sure no firewall blocks connections at the port.
I'm working on a JRE 1.6 so a sqljdbc4 should work, and I've created a working ODBC, so the server is responding, and the error should be in java command or JDBC installation.
Can anyone help me?

At the risk of stating the obvious, this looks to me as if TCP connections haven't been enabled on SQL Server. You have to manually enable them, they don't come enabled by default.
There's an article on MSDN here which explains how to enable TCP protocols for SQL 2005/2008.

Following are the quick trouble shooters:
Try to connect to your server using external front end.
Check if your firewall blocks the connection to the port
Check to see if server is really up.
A Suggestion :
If you are using eclipse , you don't need to add the jar into CLASSPATH variable , you can just add it in library of your project to make it available at runtime
