Without knowing what popper program you're using (Qualcom?), all I can
tell you is that the program probably tried and failed to lookup the DNS
PTR record for the connecting host's IP address.

This would happen if the client's IP address doesn't reverse resolve
(no PTR records) or if your host's DNS is broken. Try resolving the
hostname yourself.

If valid client hosts don't have PTR records and you can't or don't want
to add them, you should read the documentation for your popper to find a
way to turn off DNS reverse-resolution.

Ciao,
Sheldon.
