While trying to clone an already existing repository from gitlab into my local drive. I used the format
$ git clone https://github.com/libgit2/libgit2 mylibgit
The resulting folder e.g mylibgit was found somewhere outside the XAMPP web folder (i.e htdocs), I moved it there but it's not working as supposed.
I moved it out to my desktop and got the error :
fatal: unable to access 'https://git@gitlab.com:xxxxx/yyyyyy/':Port number ended with 'y'
Gitlab actually requires a user when using deploy tokens. For me, this was caused by mixing in ssh syntax as http://<user>:<pass>@gitlab.com:repo instead of gitlab.com/repo.
if you change your remote from using ssh to https and accidentally leave a colon in the string - you will a message like this. It's a confusing message, but it makes sense once you understand the source of the problem.
I had similar problem. Just corrected(removed git@ and port number) URL in .git/config file and it worked.
[remote "origin"] url = https://git@gitlab.com:xxxxx/yyyyyy/
To
[remote "origin"] url = https://gitlab.com/yyyyyy/
