How to resolve Gateway appliance cloud connectivity failure - version 1.10 and newer

Note: With Gateway 1.10 installed, the NUC takes up to 8 minutes to initialize. The Dell takes just a few minutes.

Symptoms

• When you are connected to the private network on the LAN2/Gb2 port, the Gateway login screen does not appear. The spinner is stuck.

• You can connect to the private network interface but the public network connection is down and the Gateway application is unreachable.

Resolution

The most likely cause is a network conflict.

• Make sure your network cables are properly connected.

• Adjust your network settings to eliminate any network overlap. 

• If you chose a nondefault Gateway appliance private network IP address, make sure the Gateway appliance private network IP address is not part of the DHCP scope; that is, the Gateway's IP address should not fall in the range defined by the DHCP starting and ending IP addresses.

Changes might require restarting the DHCP server.
