Cannot install repository on Forge site

When I attempt to do this, I get a "That repository name is invalid or you do not have permission to access it." error. These are the steps that I have taken so far. I have added the SSH key from the server as a deploy key in Gitlab. I tested that this works by calling git clone [email protected]:username/repo-name.git on the server and it cloned the repo as expected. I have tried to delete the site and recreate it. I have tried refreshing the Gitlab Token. None of these solutions fixed my problem. I am also using this repo on another site on a different server, however for that site, I am using the 'develop' branch and for this site, I want to use the 'master' branch. Is there anything else that I did not try to fix this issue? Any help you can provide will be greatly appreciated!
