Trouble with URL Directs

Hi,
I’ve attempted to RTM and other forum posts, but have not found a clear solution.

I set up a gitlab server, and everything is working nicely except url directs.
I have a domain, say, git.domain.com, set as the external url, but everything from the domain automatically is redirecting to git.domain.com, i.e. domain.com redirects to git.domain.com.

The only thing that looked like it would work is to use an external web server or maybe make my own nginx server block files and turn off the nginx settings in the gitlab.rb file, but that seems to be overcomplicating things. I would also like to keep the awesome one and done settings for Let’s encrypt (an awesome feature!).

Any help would be appreciated,
Thanks!
