Nextcloud OAuth2 callback does nothing

Support
1

My version of HedgeDoc is: 1.9.9

What I expected to happen:

Be logged in using Nextcloud OAuth2

What actually happened:

Nothing

Hello.
I am using version 1.9.9 of HedgeDoc, which I successfully deployed using Dokku.
I configured Nextcloud’s OAuth2 authentication and the URLs are correct, but when I return to the callback URL nothing happens, the application continues to show the Login button.

Can anyone help me figure out how to make this work?

It’s not working in docker-compose deploys too.

It sounds like the reverse proxy isn’t configured properly. We have seen this issue multiple times when reverse peoxies weren’t communicating that a connection was done over HTTPS. See our docs: Reverse Proxy - HedgeDoc

Thank you.
I copied the nginx config from the website but the error still occurs.
The authentication works on hosts that do not use a reverse proxy, so I don’t know what I have to change in reverse proxy config.

I’m sorry, My mistake.

The solution was disabling SSL since it’s managed in my reverse proxy host.
Thank you.

CMD_PROTOCOL_USESSL=false

It’s not 100% solved.
If I turn on CMD_PROTOCOL_USESSL, OAuth2 doesn’t work.
If I turn off CMD_PROTOCOL_USESSL, OAuth2 works but I got mixed content (https and http).
