Glad to hear that it's working right now.
Artnet is a bit tricky in first understanding, but once understood very easy to configure.
Artnet uses 16 Universes per Subnet where 0 ist the first Universe and 15 the last in the Subnet.

Also first Subnet is 0

Catalyst counts through means e.g. Catalyst Artnet Universe 17 is Artnet Universe 2 in Subnet 1.

Best
