Discover scanners sometimes fail to connect to Discover detection servers with multiple NICs installed.

This issue may be cause by a loopback IP used in one of the sockets: 127.0.0.1:8090 and 169.254.21.249:8090, for example.

To address this issue, take one of the following actions:

• Swap the configuration of the interfaces (eth1 <-> eth2)
• Deselect TCP/IP on the second interface configuration. The second interface can then be used for network capture, but not for L3 network connectivity.
