Can't clone, push, pull from remote

Suddenly a few days ago after about a month of working fine, gitlab 2.5.2 installed on ubuntu 12.04 no longer performs clone, push, or pull requests. the response is always the same:

The project you were looking for could not be found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights

I even installed gitlab on a windows machine and tried to access my repository with no luck.

Any suggestions?
