Error retrieving the token

Troubleshooting

Hi @ahmaddanial

Thanks you for your answer.

  • Looks to me like we were on version 5.22 but I’m not sure there is a way to check this?
  • The error appears when authenticating with Gitlab, once I click on “Sign in” to login. By randomly I mean that sometimes I click on “Sign in” and this error does not appear. So if we’re already connected, we don’t get the error until at least the next reconnection if we’re unlucky.
  • In mattermost.log I have errors like:

{“level”:“error”,“ts”:1599722273.8641682,“caller”:“web/oauth.go:278”,“msg”:“AuthorizeOAuthUser: Erreur lors de la récupération du jeton, response_body={"error":"invalid_grant","error_description":"The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client."}, status_code=401”}

I watched this one: Mattermost - Token Request Failed when using Gitlab SSO (#2984) · Issues · GitLab.org / omnibus-gitlab · GitLab but that doesn’t mean anything to me, especially since I’m a novice in the field…

I also looked this one: [SOLVED] Mattermost Gitlab - Token request failed but I don’t have quite the same thing even though there it is looks like.
