Couldn’t log in with IP or umbrel.local but could ssh in.
Re-flashed and still can’t get to dashboard so then I try to ssh in and now I get this message.

The ECDSA host key for umbrel.local has changed,

It is also possible that a host key has just been changed.

@louneskmt you can rename this topic to something like @ WARNING: POSSIBLE DNS SPOOFING DETECTED! @, that can be useful to searches, as this issue is very common.
That is your path on Mac. @louneskmt took the path from your post that came from your Mac telling you where the file is located. If you’re trying to find the file in Finder, you must enable hidden files to see it because it begins with period. Open Finder, go to your home directory ryanb and press Shift-Command-. (period), you’ll find .ssh directory.
Another way of doing it is through Terminal, type ls -a will show you hidden and non-hidden files/directories. Quickest way to do it is nano ~/.ssh/known_hosts remove the line with Ctrl+K, save with Ctrl+X, Y, return
Antonios-MBP:~ antonio$ ssh -t umbrel@umbrel.local

Could I get help please I’m trying to connect the the SSH so I can change my username on my node
Is there before and after command prompt screen examples I could use. I see the known_hosts part in the Alert I get in response to me ssh into Umbrel, but how do I go about ‘deleting that file’.
Your path to the file looks wrong. I believe it should be C:\Users\itadmin\ssh\known_hosts
Based on the response from SSH, it’s attempting to resolve the hostname “known_hosts” as if you gave it the command ssh known_hosts if you’re trying to delete the file, you can use Windows Explorer to navigate to that directory and delete the file.
