Check with "ssh -v" that you really are connecting to 213.171.194.64 when you ssh to the host name. isbd.biz also has an AAAA record of 2a00:1098:82::6:1 - is that actually the same host? Easier to typo an IPv6 address. "host" is reporting what is in DNS but your system uses its own name service so if you have piut an entry in, say, /etc/hosts for example, this can confuse things. So does: $ getent hosts isbd.biz return what you expect? If you are logged in to the VPS and watching its logs, what happens when you do a (failed) SSH connection by host name? If you don't see the attempt and failure, you're not connecting to the same host. An ssh config entry for isbd.biz can also override DNS. ssh -v will enlighten you if so.
