ERROR: Repository not found. fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists.
Resolution
The most obvious first solution is to ensure you actually do have the right username and password entered to connect to the private repository
Next, check to ensure you've configured Plesk to use SSH connectivity mode -- this is required for private repositories
Finally, ensure that you do not have ".git" at the end of the repo name like the above error shows. Remove the ".git" so the ending looks like /repo/
