Can’t make gitlab mattermost work!

Hi, I add mattermost_external_url ‘’ , but the mattermost can’t work well , notice:{“id”:“api.context.404.app_error”,“message”:“Sorry, we could not find the page.”,“detailed_error”:“There doesn’t appear to be an api call for the url=’/api/v3/oauth/gitlab/’. Typo? are you missing a team_id or user_id as part of the url?”,“request_id”:"",“status_code”:404,“is_oauth”:false}

i try to delete the mattermost database and data folder , but not work also

Hi @xrain0610,

Are you able to load Mattermost at all? When does that error occur?

Also looking at the Mattermost log file might help you out. It should be located here on a default GitLab install /opt/gitlab/embedded/bin/mattermost/mattermost.log
