I have been using a Git repository for a couple years and still feel like a newb.. help is most welcome!

Posting here because this was one of the first Google results for 'RPC failed; result=56, HTTP code = 200'.
I tried many different things to get this issue resolved. I tried compiling git from source, adding gitconfig settings, and I even tried multiple configurations of my GitLab server. None of these things worked. I didn't understand why I could clone a repo successfully on the same subnet as my git server, but couldn't over a remote subnet (connected by site-to-site VPN).
The issue ended up being my firewall. I white-listed the client and everything started working. Temporarily placing the client in a DMZ may also be a quick fix.
