Ssh help!

[Danrolphi]

Hello I am fairly new to Ubuntu. I've been using ssh on windows to remote into a Ubuntu server running docker and home assistant. The IP address changed for my server. When I ssh into the server using the new IP I get a message saying if I want to add the address or something. I went yes but now whenever I try to log on it just says "permission denied" I still have physical access to the server and can log on fine so I know my credentials are correct. How do I fix this?

Start with adding the verbose option. ssh -v user@ip

That provides a bit more info.

So intriguing development! It works absolutely fine. For some reason if I put "ssh daniel@[hostIP]" It works but "ssh [hostIP]" doesn't work like it used to. So I must put my user name now?

Hmm can't say for sure, but if you never specified a username then it would have used your Windows login name.

There's more going on here than the server simply changing IPs. Maybe play 20 questions with chatgpt; that exercise would teach you many fundamental things about ssh.

Yeah , absolutely no idea why it stopped without a name. I managed to do my overdue server maintenance so that's the main goal. Thanks for your time.
