Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. with FF version 26.0 and selenium standalone jar 2.39
I am trying to connect to selenium 2.30 with FF version 26.0 installed in my AWS unix machine but I am getting below error when I start both my client which access selenium.
Also, when I try the same with selenium standalone jar 2.38.0, it works fine but suddenely after some time in a day or two, it starts giving below error with 2.38.0 as well. Not sure why this is happening? Any idea??
project is I have a multithreadin app wherein client keeps executing some threads which pings some URLS and all, it keeps on happening unless some issue like below occurs.

Answer
Update your selenium jars. The new version of firefox(Or different browser) is not supporting old jars of selenium.
Download both Selenium Server (formerly the Selenium RC Server) Selenium Client & WebDriver Language Bindings
Replace them with old jars you are using. Update your mozilla also so you can get the updated results
