Socket Exception - Address: 184.108.40.206 System.Net.Sockets.SocketException (0x80004005): The requested name is valid, but no data of the requested type was found
at System.Net.Dns.InternalGetHostByAddress(IPAddress address, Boolean includeIPv6)
at System.Net.Dns.GetHostEntry(IPAddress address)

The most likely cause is a defined Operator Panel has a hostname which can no longer be resolved on your network
Ensure communication to all defined Operator Panels is working by pinging each one. Also check to make sure the defined configuration of the operator panels is correct.
