Hi,
I just installed gitlab with LDAP (9.5.5-ce, working fine), installed Mattermost (4.2.0, without gitlab first, also fine with nginx ) and now I wanted to connect both. Everything is on Debian Stretch KVM VM.
I added the application manually in gitlab and copied the authentication stuff to mattermost. I got redirected correctly to gitlab and after clicking on the gitlab authorize button, i’ll get redirected back to mattermost and end in an 500. The log states stack trace error. I also reinstalled the mattermost server twice and setup everything again, but still this hard error:

Any idea how to debug deeper? What can I do?
Accoding to nginx’s access.log
, the request also looks fine:
