Many thanks in advance.
It sounds like the host you're trying to SSH from doesn't know what address the other host's name is at. Do you know if you're using a DNS server to map hostnames to IP addresses, or are you just keeping that in your /etc/hosts file?
If you're not sure, then updating /etc/hosts with the hostname and IP address will probably suffice. Any time you type a hostname, your system needs to translate that to an IP address before it can communicate. Most systems use that file to map names to addresses.
