My git client is behind a company proxy. That proxy makes ssl interception.
I managed to suppress the SSL Certificate Problems with git config --global http.sslcainfo PATH-TO-PROXY-CA-CERT
Now I can clone repositories from github/bitbucket/gitlab/... over https (ssh is blocked)
But whenever I have to authenticate (e.g. for private repos or to push something) I get the message fatal: Authentication failed for ...
sometimes also
remote: Anonymous access to ... denied.
fatal: Authentication failed for '...'
Why do I get these errors and what can I do to make it work?
Solution: In this case the company proxy removed the credentials for security reasons.
