Nextcloud 22 Oauth2 and Moodle

Nextcloud version: 22.1.1
Operating system and version: Debian 10 buster
Apache or nginx version : nginx 1.14.2
PHP version : 7.3

The issue you are facing:

I get a « unable to upgrade token » error when connecting NC Oauth2 API with moodle.

Is this the first time you’ve seen this error? : Yes.

Steps to replicate it:

  1. Use moodle 3.11.2 and Nextcloud 21.X (everything is fine)
  2. Migrate to NC 22.
  3. Attempt an Oauth2 login on Moodle.

The Oauth2 service from NC works well with other clients (e.g. Hedgedoc).
The Moodle Oauth2 mechanism works well with other clients (e.g. google).

One thing that I had to redact, that seems odd, is that the client id is said to be wrong, although it is accurately written.

Endpoints are also accurately written (as of the latest documentation availlable).

Any clues on what to do?



Update: I have attempted the same task (Oauth login on Moodle) on a fresh install for both Nextcloud 21.04 and Moodle 3.11.3 (latest moodle) and it works. Thus, it seems that something was lost in the Upgrade from NC 21 → NC 22.

I can confirm the problem with a fresh install of Moodle and NC 22.
We would really like to connect Nextcloud to Moodle for some schools, but if we can’t upgrade without loosing this connections then we need to look for another solution … :frowning_face:


See if this issue is what you are experiencing.

thanks for your reply. I have read the thread and it seems pretty close. However, the error message is not the same as OP (maybe because the login problem is with RocketChat instead of Moodle). I will report this page to the thread, though.



If it is not the same I recommend opening a new issue. You can mention the existing issue in github with #issuenumber

The issue was resolved two upgrades ago. Thanks!
