I just did a fresh install for Moodle 3.3 as I'm a big fan of using Oauth for authenticating my users. I used a plugin in prior versions, but since it became a core plugin in 3.3 and on, I just did a fresh install and hope to be migrating my courses soon.
I followed instructions from https://docs.moodle.org/dev/OAuth2_Services. My users started creating accounts normally, but now all I get is the following message:
error/Could not upgrade oauth token
I tried to recreate / update the setting at the Oauth2 services page, but as you can see in the image attached, Moodle seems to be unable to do Discovery nor connect to the System Account. I also attached my current settings. Is there anything I could do to fix this issue?
thanls in advance,
