Hello, OS: CentOS 7 Nginx 1.12.2 Node: v8.11.3 RocketChat: 0.69.1 RocketChat Android App: 2.5.1 Build 2036 SSL Cert from Let´s Encrypt After all set, i cannot view the Chats in Android APP.

The error your seeing in the logs looks like errors coming from web client. Can you check your connection log in your browser console? From there look and see if a websocket connection is being made. To bring that up right click and inspect page, then go to the network tab. Once that’s open reload the page. ---

Can you switch to the console tab and paste: `new WebSocket('wss://{your server}/websocket');` of course replacing `{your server}` with your servers hostname. Let me know what it spits out. ---

Can’t tell from this exactly whats happening try: sock = new WebSocket(‘wss://nexxus.nuvem.top/websocket’); sock.onerror = function(err) { console.log(err); }; That should log an error then if there is one. Give it a few minutes. ---

What about the output of: `export HOST={your host here} && curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host: $HOST" -H "Origin: $HOST" -H "Sec-WebSocket-Key: fVXESE8fjBMx8HheW0YlZQ==" -H "Sec-WebSocket-Version: 13" https://$HOST/websocket` ---

Okay – I tested his config with curl – and it worked – HOWEVER it seems to be failing – he’s using verbatim the working config from my server – and it should work…but it’s not…not sure what’s up ---

~~OK this is good! Lets see if the mobile team has any ideas, it could be on that end now that we know everything with your websocket is good~~ looks like websocket connections are actually returning 400 bad request. After some discussion on [#support](https://open.rocket.chat/channel/support) all is resolved. Seems double reverse proxy due to a network device ---

In the end the problem was with my Firewall / UTM. I needed to enable WebSocket passthrough and it was disabled.
