Firefox can't establish a connection to the server

[nisgupta]

We are running our automated tests on TestExecute VM machines on Firefox Browser.

Some times we get the error - Firefox can't establish a connection to the server . This error do not happen every time.

Attaching the screenshot. 

We are not able to reproduce this issue manually on those machine, . What are the causes of this error ? How it can be fixed. For developers it is false positive. 

Please update 

Thanks

I would suggest the following:

1. Make sure you have the latest version of TestComplete/Test Execute (which is 14.50)

2. Try going through this documentation article and checking whether everything is set up right - https://support.smartbear.com/testcomplete/docs/app-testing/web/general/preparing-browsers/firefox.h...

It do not help.

If this doesn't help, I think that opening a support ticket is required for a more thorough investigation.
