I get this error on a fresh install of gitlab. The message looks like:
fatal: unable to access \'https://gitlab-ci-
token:xxxxxxxxxxxxxxxxxxxx@gitlab.example.co
Had faced the same problem after enabling verbose mode by following command
export GIT_CURL_VERBOSE=1
and found the following issue:
NSS error -8179 (SEC_ERROR_UNKNOWN_ISSUER)
Found this following site helpful,But its good when you have entire control for the proxy server as well to enter the certificates.

I instead ran following command to bypass ssl verification by porxy server and it worked
git config --global http.sslVerify "false"
