Everything was working fine and I was able to push, until my personal token was expired. I tried to push and it gave me this error. I made another token and authenticated with it, but still it gave me error.
git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks push -v --tags My_Gitlab master:master
