copying ssh id from debian to centos times out, how to debug?

I'm setting up another pc on my network. it will eventually be headless.

It currently boots into the centos CLI ~ which is fine. now i want to copy over my ssh rsa key from my main debian pc to the new centos one.

I can ssh from debian to centos with 'normal password'

ssh-copy-id [userName]@$192.168.100.169

the terminal will then ask for the password, and everything is fine, however when I attempt to copy my public key to the server using

ssh-copy-id -i id_rsa.pub userName]@$192.168.100.169

the call will eventually time out... here is the output

/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: ERROR: ssh: coect to host 92.168.100.169 port 22: Coection timed out

I now that using a standard ssh login I can get the debug info, but how do I debug the ssy-copy-id command, i've tried

ssh-copy-id -i id_rsa.pub -o -v userName]@$192.168.100.169 ssh-copy-id -i id_rsa.pub -v userName]@$192.168.100.169

but I just get errors for invalid options, so I have no way to debug what isn't working.

I've done a similar thing with other virtual machines (also ruing debian) and they have copied over the rsa key almost instantly, what config option have I got that is different between debian and Centos that is causing me grief ?

All help would be much appreciated.

thanks in advance
