I have the same setup and same problem. You can check that you can establish a websocket connection. In my case websocket seems to work

HTTP/1.1 101 Switching Protocols
Server: nginx/1.14.0 (Ubuntu)
Date: Wed, 28 Aug 2019 03:42:17 GMT
Connection: upgrade
Upgrade: websocket
Sec-WebSocket-Accept: qAzJnlZp0xHyZGZ/MqIoBVuu1u8=

�o��a["{\"server_id\":\"0\"}"]

Also, use appear offline but when you check in the settings it says online so connection works but something seems to fail to work.

check that your config for your proxy server actually handle websocket request on location /websocket and /(.*)/websocket

proxy and websocket is ok, because version 3.5.0 was working fine web version works normal and uses the same websocket (I guess)

I've had this/similar issue because my Nginx reverse proxy wasn't set as per the documentation - https://rocket.chat/docs/installation/manual-installation/configuring-ssl-reverse-proxy/

I'd add that something I discovered, when configuring nginx, you may have to set some headers again in location I believe in my case it was the HOST header that would get reset if it was set on a context above but some headers would be added in location. As a result if you're using a second proxy like traefik, the host header doesn't get passed through to rocketchat.
