Error when trying to autoupdate Octoprint

[Quasimondo]

Not sure if this is the right place to post this, but when trying to run the automatic update from the Mr Beam frontend it failed this time. I think it is an issue with git on the Raspberry not having a domain associated, at least that's what I read from the log file:

The question is if there is a way to fix this from the web frontend or if I have to log into the RPi with a console and manually set those git credentials?
