I have two machines. I have gitlab repo cloned on one of them and is working just fine.
Recently I tar zipped one folder from this machine and installed the same on the other machine. (.git directory got copied along with it).

On this new machine,
git add, diff, commit and other commands worked fine; however git push did not work at all. It throws following error:

remote: The project you were looking for could not be found or you don't have permission to view it.
fatal: repository 'https://gitlab.com/<userid>/<reponame>.git/' not found

How should I approach this to get it solved. The repo is working just fine from the other machine.
