Two clients, no client-ID, still one not showing up

Hi there,

I have two local clients (Controllinos, basically Arduino Megas) that have both different Mac-adresses set, different IPs and I can ping them both with immediate response (<1ms).
As broker I have tried out the Mosca-node, which works well with only one client and aedes, where I get a "identifier rejected".

I have tried almost all possible ways to connect those two clients to the broker, so that I can see the data on the dashboard. But all I get is data off client nr. 2.

Maybe anyone has got some help for me?

Thank you in advance,
regards,
Jürgen
