I used Putty to SSH into my UTM (9.404-5) for years, no problem.
I don't know what's changed, but I can no longer log in.
I verified the RSA key is correct. I restarted SSHD, I tried using just password authentication. Nothing helps.
The error in sshd is:
basil sshd[5305]: fatal: no matching mac found: client hmac-sha1,hmac-sha1-96,hmac-md5 server umac-64-etm@openssh.com,umac-128-etm@openssh.com,hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com,umac-64@openssh.com,umac-128@openssh.com,hmac-sha2-256,hmac-sha2-512 [preauth]
I'm not sure what that error is trying to say.
