The first address in a network is not valid for a host, as it is used to identify the network.
65.110.7.20/30 breaks down like this
65.110.7.20 - Network identifier - not usable for a host
65.110.7.21 - OK to be used by a host
65.110.7.22 - OK to be used by a host
65.110.7.23 - Broadcast address for network - Not usable for a host
In reality, you only have 2 usable addresses. I bet if you set the IP to a valid host address, you will have no issues.
