I am working a project that relies on connecting iOS devices (via CocoaMQTT) to and mqtt server/broker running on a Pi.
With one iOS device things work just as they should. When I try to connect with a second iOS device, things fall apart.
The second device attempts to connect and then immediately disconnects and I get an error on the xCode console (running the second device) : "Could not resolve hostname: nodename nor servname provided, or not known"
I am new enough at this not to know if this is an issue on the Pi side or an issue on iOS side.
I wonder if anyone could point me in the direction of how to debug?
