Scenario: Authentication failed

Error message

fatal: Authentication failed for''


Check if the user ID and password are correctly entered. The user ID and password is the same as your Backlog login email address and password. 

Useful tip!

If you have set up two-factor authentication, you need to authenticate with a special password. To generate a special password, go to Personal Settings > Password

Scenario: RPC failed

error: RPC failed; curl 92 HTTP / 2 stream 0 was not closed cleanly: PROTOCOL_ERROR (err 1)


Please try the following methods. 

  • Upgrade your Git client. 
  • Run
    $ git config --global http.version HTTP / 1.1 to specify HTTP / 1.1
  • Push with SSH instead of HTTPS.
