There is an issue where the Console doesnt always show gw’s as connected - do you have a node (known good!) sending data that you can see in Application?
Also double check the MAC Addr used to register as GW (on a Pi use the Enet Mc vs WiFi MAC even if connecting on Wifi only - unless you are usinga Pi0W ofcourse.
Assume you checked legacy forwarder if using UDP when registering?
Check that is correct… and typed correctly. Most PI’s I’ve seen start B82 - though that may have changed with the Pi4 - (dont use one for a gateway yet) so am suspicious there…
Also try monitoring with ttnctl & command line… vs using console (Search forum & docs & GIYF.)
