Description Kedar Kulkarni 2017-05-24 18:19:00 UTC 
Description of problem:
As the summary states, HTML5 console does not connect to VM on very first attempt or sometimes if you close the Tab containing the Running Console(maybe by mistake) and then if you try to reopen the console for same VM again immediately, it may fail to connect.

Version-Release number of selected component (if applicable):
5.8.0.16, but this behavior was noticed in previous builds too

How reproducible:
Not sure, intermittently maybe

Steps to Reproduce:
1.Open HTML5 Console for any VM


Actual results:
May or may not connect to VM, you may see that on bottom left corner it may say Connected, but it might not show anything but a blank window, or may say disconnected. Please refer to screenshots for more info.

Expected results:
HTML5 console should behave consistently and it should connect to console all the time or show some more meaningful error text if there is an error.

Additional info:
If this bug can't be reproduced and solved, it should be noted in our official documentation as known issue. When HTML5 console connects without errors that are mentioned above, it works fine and you can use your mouse and keyboard to interact with it normally.

I am thinking this is a duplicate of the websockets issue.... bug 1404354

Please close if you agree fellas.

I believe this can be done by running the following.  If you see more than a few of this processes, it'll cause problems with the connections.  The more you see, the more likely connections will fail...

Comment 7 Kedar Kulkarni 2017-07-14 14:30:03 UTC 
Hey Dave, 

I will close it since it can not be reproduced consistently. It was about Occasionally getting "502 Error" Page when launching HTML5 Console. Also websocket workaround might have helped this improve.
