Hello,

For almost 2 years I've been using luckybackup to backup some shares from one unraid server to another.

Today my backup server doesn't accept connection from my main server.

The config didn't change. The ssh key from main server is in the authorized key on backup server and didn't change.

I wonder if there has been a recent change in ssh on unraid.

Here is my log:

it's almost as if backup server wants only password and not key.

Post the output from:

ssh -v [email protected]

i rebooted the backup server (192.168.2.52) and it's now working.

I found examples in the forum of the same symptom.
