That's not really a cockpit specific question. Do you already have a domain name on your server? If it resolves to the correct IP, what doesn't work? If you don't have a domain name, you need to set one up (this is not trivial, but also this bug tracker isn't the place to give that kind of support).

@martinpitt Yes I have a domain name configured (I already have 3 website on my VPS). But when I try to configure the redirection in the vhost (with cockpit.domain.fr) from / to http://localhost:9090/, it work for the login page, but not after (it throws an error, but when I go to the logs, there is nothing). Everything is working perfectly with https://my-ip:9090/.

The error in the console from cockpit.domain.fr :

[Error] WebSocket connection to 'wss://cockpit.domain.fr/cockpit/socket' failed: There was a bad response from the server.
[Warning] transport closed: disconnected (index.js, line 2)
[Warning] Server has closed the connection. (index.js, line 2)

Ah, you have a redirect! That's not just accessing the cockpit port with a domain name then, but it is then a reverse proxy. You need to set up cockpit.conf with Origins=, please see https://cockpit-project.org/guide/latest/cockpit.conf.5.html and https://github.com/cockpit-project/cockpit/wiki/Proxying-Cockpit-over-Apache-with-LetsEncrypt

@martinpitt I already tried that, but nothing changed!

[martinpitt]

Sorry, that needs more logs then -- from apache, from the journal, etc. I don't have further off-hand ideas, I'm afraid.

[maximehamou]

I am so sorry! I retried from zero (with just my previous config), and it worked! I think it was either a cache error, or a typing mistake.
Sorry again...

Hah nice! (Don't worry) 😁
