404 on commit to remote repo (not GitHub)

Hi,

I’m trying Stoplight as a desktop application where I’ve open a local repository that I’ve cloned from our company gerrit server.
While trying to commit (to normal refs… no review stuff for now) I get a 404 since Stoplight obviously doesn’t know my password.
Is there any configuration for this to work, or is Github the only repository that is really supported?

Regards
João
