My upgrade from C-7 to C-8 went quickly and smoothly. I have one issue that needed to be resolved. Both my C-7 (before upgrade) and C-8 are configured with a wired network and not using Wi-Fi. The local router provides DHCP and local name resolution. The router knows my hub and sets a fixed static IP address for the hub. The hub is using DHCP.
I have several rules that use HTTP Send GET. I am using the local name of the device in the URL and not the local IP address. After I upgraded, these rules on the C-8 did not work. I could not ping any local device using the local name in the Network Test ping.
To fix this and resolve this issue, I changed the Override DNS Settings to include both 192.168.1.1 and 18.104.22.168 (previously Override DNS was empty/blank). After adding the IP address for my router using this means, the apps using HTTP Send GET work as expected and the Network Test ping with local device names also works.
I don't think this behavior is correct for the C-8 since it should automatically use the DNS from the DHCP server as well as other DNS nameservers provided from DHCP. The C-7 and other computers on my local network resolve local names properly without any special direction to use the router/DHCP server as a DNS.
