I do still have my private key to match the public one already submitted 
I made a serious point of making sure I preserved everything in /home!

This is what happens, with a lot of the messages removed for brevity:

Ok, from the above I can see one or two things:

* has the ip address changed on the server? The warning says that it is 
62.141.46.210 while the second attempt is telling me it's 78.47.172.252.

* why is it telling me that the fingerprint is 
88:5e:b0:80:96:c0:e2:89:f8:52:a4:d8:a1:bc:9b:5f in the warnings and when 
I connect it says it is 91:3e:7e:28:ff:be:a5:c1:1d:f2:e1:bf:7c:ff:10:e6 
instead?

The above repeats as long as I want to keep trying. The warnings say one 
things the connection says another - and the end result is the same, I 
don't get a connection.

If I ping the server I get 78.47.172.252 - so the warnings appear to be 
a pile of poo!

I'll keep investigating ....


Cheers,
Norm.
