We experience an issue when installing a Qlik Sense 2.1.1 on a Windows Server 2012 R2.
Basically, all is working fine with HTTPS.
In HTTP mode, all is working if we don’t use 80 port. We try 82 and all is ok.
More elements that we found during analysis:
Moreover, firefox devtools tell us that websocket connection was interrupted :
Did someone already experience this issue and found a solution ?
I've seen some question/answer with the same problem but the discussion stop when server is working on another port, but we want it to work on 80.
i'm use Sense server on 81 port http. http://bi.prozorro.org:81/hub
And yes, I also have a similar error occurs. But I can not understand the law of manifestation.
connection may break off immediately after connection and after 30 or 60 minutes.
