Strange Problem with Passwordless Login to Client

Just setting up a new Vero 4K Kodi machine and had a problem (my errors probably) with passwordless login so I started over by removing client /home/osmc/.ssh file and also my server /.ssh info so I could get rid of all the old rubbish.
Ran ssh-keygen etc and then created ./ssh on client machine and uploaded generated public key and having completed the process was able to log in without password (using an example crib).
My question is, that although I log in to the machine at 192.168.169.144, I get a message with the last login message as follows:-

Is this a line of text from some previous effort of mine which just happens to have the wrong (ie .134 not .144)IP?

Another question is that my public key file is named “authorized_keys” not id_rsa.pub and there is no authorized_keys directory. Is this an artifact of a slightly different ssh approach or from an old example?

Sorry I couldn’t edit in time. Please ignore my question.
