### Description

I installed the rocket.chat server, using snaps, several times quite successfully, including authentication with the rocket.chat cloud. But it was only after configuring Nginx to use a commercial SSL that the ability to authorize the server’s access to the Rocket.Chat cloud broke.

All clients fail to authenticate, but when the web client fails, it comes back with this error:  
[http://localhost/admin/cloud/oauth-callback?code=ebTB9hM7QdPoxYEk0Z4B&state=YPNi2XchenqXcuKge](http://localhost/admin/cloud/oauth-callback?code=ebTB9hM7QdPoxYEk0Z4B&state=YPNi2XchenqXcuKge)

The server status had the following errort:  
Jan 13 14:44:31 rocketchat rocketchat-server.rocketchat-server[1527]: Failed to get AccessToken from Rocket.Chat Cloud. Error: oauth\_invalid\_cli\>  
Jan 13 14:44:31 rocketchat rocketchat-server.rocketchat-server[1527]: Server has been unregistered from cloud

Any advice appreciated. First time installing rocket.chat, so it’s possible that I’ve made a stupid mistake, particularly in the nginx config file.

Fixed it. I needed to change the URL from [http://localhost](http://localhost) to [https://example.com](https://example.com)

The problem was that HTTP calls were not being redirected to HTTPS.
