Hi @elias,
Thanks for you reply. To be honest, I don’t know where to check that.
Behind the firewall
Since I have limited access I can only ask someone to do debugging for me - like the screenshots linked above.
Based on the experience with wss test website, the headers required for wss are forwarded. Is there any header in particular that might cause this but it’s not required for basic wss but required by Mattermost?
At the server level
I have no idea where can I see this in Mattermost, since there is nothing in between.
Should I change the log level in Mattermost?
