Google Compute Engine not working well with Buddy

Hey, I am trying to build a simple pipeline that uploads with rsync the git repo to my vm instance inside of google compute engine.
I tried everything to make Buddy work, tried to add the buddy ssh key to the server directly, running the command buddy provides on the server, creating my own ssh key, uploading it to the server.
for some reason, they key only works for one per action. the error message I get the error: Server response: No more authentication methods available.

Don’t know what to do
