Enabling HTTPS for Geonetwork 4.2.2 does not work with OAUTH2 OpenID Connect

After successfully implemented the install of SSL certificates in the server, Geonetwork can now be accessed through https://domain/geonetwork

However, when clicking on the 'Sign in' button, an error is displayed on the screen showing the following URL:

`http://domain/geonetwork/login/oauth2/code/geonetwork-oicd`

So, the above URL is using **http** instead, not https, not sure why, or if this misconfiguration is causing the OpenID Connect to fail.

I have changed in the database the values for `system/server/port` and `system/server/protocol` but these ones do not seem to have any effect in the above error.

Besides, the parameter: `OPENIDCONNECT_IDTOKENROLELOCATION` not sure how to configure it, where could I find an example of this value?

Thanks,

Start by reproducing the HTTPS sign-in flow and inspect the generated OAuth2 callback URL, which the issue reports as using http instead of https. Review the GeoNetwork HTTPS and OpenID Connect configuration and determine how OPENIDCONNECT_IDTOKENROLELOCATION should be set. Done means the callback uses https and the role-location setting is documented with a working example.
