Unity Cloud Build + Gitlab CE = Repo is not accessible
Hello,
I have a Unity 5.5 project using Services/Cloud Build. The project is on a self-hosted gitlab CE server (8.14.3) on a VM running Ubuntu 16.04.
I am trying to use the Cloud Build service to create a Windows x64 .exe. I get to the first step of setting up the server URL using a git@... styled address. I choose git as SCM type. I then receive an SSH key, which I copy/paste to my GitLab project, under deploy keys, named "Unity". The key is accepted, however, Unity Cloud Build can still not see the repo and tells me that "Repo is not accessible. Please check your URL and repo settings."
The URL seems to be accessible. I find that under repo settings, visibility is set to private (which I cannot change, because even though I am an owner, it's under someone else's account). Could this be the cause?
I found no relevant answers in SO. Around the net, I found this with suggestions that I followed, changing the address from http to git (https://forum.unity3d.com/threads/unity-cloud-build-update-4.284089/).
