Password prompt with publickey configured

[mahoromax]

Hi there,

I'm having trouble to connect to the remote host.
I have setup my publickey in the config, and also setup my ssh config to link to it.
In the addon protocol I can see that the publickey has been added, but whenever I try to connect I get a password prompt (without the option to configure a password anywhere (tried the one for my HAS loging - nope).

I tested via plain ssh and with vs code, same result.
I also tested with my existing user on HAS and root as Username, no changes.
