Access tokens suddenly invalid since yesterday?

Hey all, we use the GitLab API and wondering if anyone else experienced this/could shed some light on what happened. It seemed like all of our users that integrated with GitLab suddenly had their tokens invalidated for no apparent reason:

401 {error: invalid_token}, {error_description: Token is expired. You can either do re-authorization or token refresh.}

Anyone else have this happen or know what is going on? I don’t think we have mandatory token refresh enabled (but verifying that).

It’s very likely that you’re experiencing this because of a change that went into effect recently from GitLab 15.0: GitLab.com is moving to 15.0 with a few breaking changes | GitLab

Tokens now automatically are set to expire after 2 hours, so you’ll need to implement token refresh.
