问题
I'm working on Selenium and I currently have a hub connected to two vms running linux with all the browsers.
I was able to launch browsers until suddenly it just stopped . Firefox or any of the other browsers don't launch. I get the following error.
Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms.
I am running Selenium-server-standalone 2.26 with firefox 16.0.2 .
Please help.

Try running this before you start your Selenium server:
export DISPLAY=:0
