SmartServer IoT Cannot Be Reached
When you first access your SmartServer, follow the procedure in the Configuring the SmartServer IoT IP Address and Hostname section to change the LAN/WAN ports that you are using from Startup Mode to Static IP Address or DHCP. Failure to do so may result in flaky Ethernet connections especially if you unplug and re-plug in the SmartServer, or if there are issues on the Ethernet connection. This type of problem can happen because startup mode looks for DHCP, and if not found, it falls back to a static IP address.
Therefore, if you experience issues on the Ethernet channel, or if you unplug and re-plug in the Ethernet cable, then the SmartServer may not know whether it is using DHCP or static IP addresses. Changing the Ethernet ports to Static IP Address or DHCP when you first access the SmartServer eliminates this problem.
