[Plesk] WebService is not working properly

[lfernandes]

Describe the bug

I have deployed Chatwoot as a Docker container inside a webhost managed by Plesk.

All the system is working well, except for the WebSocket. The console keeps logging an error: WebSocket connection to 'wss://mysite.com/cable' failed:

Here is my nginx config:
location /cable {
proxy_pass http://0.0.0.0:43321;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}

To Reproduce

1. Install Linux
2. Install Plesk
3. Create a docker instance of Chatwoot
4. Use Plesk UI to create your domain
5. Add in "Docker Proxy Rules" your Chatwoot container

Expected behavior

Have the websocket working properly to keep the website live udpated

Moving to Q&A as we don't officially support Plesk.
