name resolution isn't the problem as I can nslookup both ways without problems
Can you provide more detail here regarding what tests you performed? Long delays are usually a timeout on a reverse DNS lookup (that is, a PTR lookup) on the connecting IP address.
Connect to the server, and get the address that the server sees as its peer either from the log or using "ss -o state established -t". Use "time host $ip" to test the reverse lookup. Send the output to the list.
