I don’t have a proxy in place, and I’m at the current version, so I can’t update right now.
When I go to https://new.mydomain.com/myteam I get directed to the correct "Sign in to myteam on gitlab mattermost ‘with gitlab’ ". When I click Sign in with gitlab, I get directed to the Profile Settings page with this error “An error has occurred, The redirect URI included is not valid.” I did run gitlab-ctl reconfigure after the change to gitlab.rb. Not sure what else I can try right now. Any ideas?
