ARP could not resolve MAC from IP (bad IP address, not part of a

-48
Error during ARP operation: the response to the ARP request did
not arrive to the module after a user-adjustable ARP Timeout.
Note: When the Client gets error -47 or -48, it uses the adjustable ARP Timeout parameter in the
configuration file to set an amount of time to wait before trying again to connect to this non-existent
server. This feature allows the Client to continue sending commands and polling other existing
servers, while waiting for the non-existent server to appear on the network.
