I have found that after the attack to DNS servers in the US, gitrefresh operation seems to be blocked. Got the error:
error: The requested URL returned error: 403 Forbidden while accessing https://github.com/Novarizark/project/info/refs
fatal: HTTP request failed
Then found this in stackoverflow
http://stackoverflow.com/questions/7438313/pushing-to-git-returning-error-code-403-fatal-http-request-failed
change the https method to ssh method really solved the probleme. Although, I am still confused why this problem happens…
