GCS StatusRuntimeException: UNAVAILABLE

We are using Google Cloud Speech API in our project and it is throwing
this exception. Can someone help to figure out what is the problem?

Network is unreachable (connect failed) means that gRPC was unable to establish a TCP connection. You should check your network settings and make sure you weren't experiencing a network failure.

Opening URL Connection within websphere

I have a local websphere server that I want to use to pull content from a webpage. when I make a get request to the server, I get a huge error. It seems to be getting triggered by getting the input stream from the connection..
Here's my code (not actually trying to read from google it's just a placeholder)
URL url = new URL("https://google.ca");
URLConnection conn = url.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
It only breaks when I enter the third line, I get this error

any help would be greatly appreciated.

Likely a firewall issue, the TCP connect() to google.ca timed out. You'd probably meet the same result If you can test outside of the application server on the same system.

Why I cannot send email via Log4j SMTPAppender?

I use Log4j 1.2.17 for loggining. I want to send error message to my email but I have some problems.
Here is my properies file:
log4j.appender.email=org.apache.log4j.net.SMTPAppender
log4j.appender.email.Threshold=WARN
log4j.appender.email.SMTPHost=smtp.gmail.com
log4j.appender.email.SMTPUsername=myGmailAddress
log4j.appender.email.SMTPPassword=passwordToMyGmailAddress
log4j.appender.email.From=myGmailAddress
log4j.appender.email.To=anotherGmailAddress
log4j.appender.email.Subject=Log of messages
log4j.appender.email.layout=org.apache.log4j.SimpleLayout
Where myGmailAddress and passwordToMyGmailAddress are my valid gmail and password. anotherGmailAddress - another valid gmail
When I run my app I get this:
log4j:ERROR Error occured while sending e-mail notification.

I spent several hours when tried to solve this, but I do not found solution.
I tried to change port, disable Antivirus&Firewall, use custom SMTPAppender etc...But it did not help...
Any ideas how to solve this?

BoneCP will not return or throw if connections are invalid

Using BoneCp 0.7.1
I setup my application and everything is working fine, but then the DB went offline.
On the next application request getConnection() started throwing internal exceptions and the retry mechanism kicked in but getConnection() never returned leaving the thread hanging.
The below exception gets thrown over and over but you would expect getConnection() to return NULL or throw an SQLException at least so you can handle it.
This seems similar: http://jolbox.com/forum/viewtopic.php?t=339&p=1390 But my problem arise after connections are established.
Also saw this... BoneCP doesn't recover from broken connection
I will try 8.0-rc1

Tried 8.0-rc2 same issue getConnection() wont return.

Old question, but may I suggest trying HikariCP for improved recoverability.

RMI timeout from remote machime

I could connect to the RMI server with my client code in the same machine. But when I access it over the internet from another machine I get timeout exception after few minutes.

What should I check now.
Thanks.

"...over the internet from another machine..." - is your server behind a router? You'll have to forward ports in this case. This would explain why it works locally but not remotely.
