I'm having trouble signing in via gitlab and github.
On the sign in page, if I try to sign in via gitlab and from gitlab via github, I'm successfully logged in to gitlab but redirected to plain
gitlab.com not githost. If I go back to my githost manually I'm not logged in. I can reproduce it consistently whereas it consistently works for my colleague with his account. I've tried clearing all cookies etc. and it doesn't help.
Any ideas for how I get to log in?
