Gitlab Repository error

When Adding repository link this error pops up, Can someone help me?  
![|1x16](http://localhost:5555/static/3107379c/images/none.gif)Failed to connect to repository : Command "C:\Program Files\Git\mingw64\bin\git.exe ls-remote -h -- HEAD" returned status code 128:

Usually that means you need to define a Jenkins credential that has access to that repository.

Thanks for answer, but i have done everything that, i have working repository from gitlab with same credentials but for different repo but it is not working on this repo

Permissions are set per repo, if you have another repository working, then it means that the user you are trying to use does not have the access permissions for the repo you are trying to access.
