Selenium standalone server not starting on VPS

[André Roggeri Campos]

I'm running into trouble while starting selenium standalone server on my VPS

root@PIV:/usr/share/nginx/pivdev/tests# java -jar selenium-server.jar 

Output:

21:53:08.857 INFO - Launching a standalone Selenium Server
21:53:08.911 INFO - Java: Oracle Corporation 24.79-b02
21:53:08.914 INFO - OS: Linux 3.13.0-52-generic amd64

No more output after that. Locally the same command works like like a charm. Any hint how to fix this issue ?

Java

Andre,

Does the server respond to any of the automation tests run against it ?

Thanks & Regards

No, it fails saying that it can't connect (I'm using codeception )

[Codeception\Exception\ConnectionException]

  Please make sure that Selenium Server or PhantomJS is running.       

I've also checked the netstat to check if the server is running, and the port 4444 isn't open

Andre,

This seems to be something that is unique to your environment, so I am fast running out of debugging options here :)

Btw, can you please check if port 4444 is blocked or something.

You could alternatively try having the selenium server listen on port 8080 which is normally open and see if that helps!

Thanks & Regards
