How to fix 'The project you were looking for could not be found' when using git clone

I am trying to clone a project from gitlab to my local machine. I have been granted rights as a developer, and use the command 'git clone

None of the protocols work (ssh and https neither work)
The error message I am getting:

remote: The project you were looking for could not be found. fatal: repository ‘https://gitlab.com/KZA_Connected/skilltree.git/’ not found

Any help would be highly appreciated.

Today, I was having the same issue. The repo was working fine at my home machine, but when I tried the same repo in other machine I started facing the same error. I was using the below URL

https://gitlab.com/{gitlab_user}/project_repo.git
And now I changed above URL to below

https://{gitlab_user}@gitlab.com/gitlab_user/project_repo.git
And it worked for me. Above solution was found at below URL

Thank you so much. It is really helpful for me.
