Help a newbie

I need help -

I need to know how to unpick our Github - Someone set it up, and i’m now trying to sort certificates.

Limitations - I do not have an admin account on the console - Is there any way around this?

My main issue is certificates - We have a wildcard certificate, which has expired. I have the new one.

2nd issue - I can’t restart the server - i do that, and we lose github… I’ve looked that up and tired multiple fixes - the one that works, is restore to the pre-change snapshot. All others give em a blank page…

Now, i can find my way around linux a bit, but i’ve setup apache only… I’ll admit to being new to both.

If i look at the gitlab.rb file:

ssl certificate and certificate key are both in /etc/gitlab/ssl/

I replace, no change
