Getting "Drop uplink message" with "Join server not found" in V3

I have a rak 7258 gateway connected to stack v3. Gateway is connected but reports “Drop uplink message” with data showing “Join server not found” when client attempts to join.

I’m running in docker.

Any ideas ?

Hi dbrosy. By client do you mean device?

Can you post your device information?

Are you using an external join server?

If you can share the settings you’re using to connect the client, it will be easier to help.
