Question

I did push origin master and after that I have an error:

$ git push origin master

fatal:
https://github.com/myusername/my-first-project-test.git/info/refs not
found: did you run git update-server-info on the server?

I did:

$ git update-server-info

but it doesn’t help at all.

Answer 1

This seems to be an authorization problem.

I would suggest you try to use the ssh protocol rather than https:

[e-mail]:<user>/<reponame>.git 

(source)

Also, make sure that in your global .gitconfig you have

[http]
      sslVerify = true

You can fix that from the command line by issuing

git config --global http.sslVerify true
