Mattermost behind Apache Proxy - wss not working

Hello @richardsonje

Can you please describe the complete solution? I’m in the same situation and been struggling for a while.
I keep getting the Bad Request error in the nginx access logs.

GET /api/v4/websocket HTTP/1.1" 400 193 

The interesting thing is that it’s working from time to time and the red top error disappears for a few minutes then it’s back.

What do you mean by “removing the nginx proxy from the mattermost VM”?
If I stop nginx proxy on the mattermost server I get the
Service Unavailable error.

Thanks for your help,
Istvan.
