nslookup <numerical address>

As I said, a DNS problem which you really should fix or let fix by your
local admin.  localhost should be resolved to 127.0.0.1 (IPv4) and/or
::1 (IPv6).  It's resolved to 192.168.1.1 plus a port number 53 which is
very wrong.  sshd will make a reverse lookup for 192.168.1.1, get a
machine name different from localhost and complains correctly about a
host name/address mismatch.
