Diagnostics ARP Table 504 Nginx Gateway Timeout

There are some ips which do not resolve as they are out of dhcp range and not static or the device doesn't tell a hostname. But almost all ips resolve proper.

If domain override exists with the lookup server pointing to itself, it causes the problem. Guess pfsense gets into a loop "ask itself many times" for the entries it can't resolve.
