ha-bridge: After jar 5.3.0 and Physical Harmony Hub Alexa no longer discovers devices

I have seen a few threads on this, but still nothing that has helped me get discovering working again.

I did read about multiple upnp devices, but not sure how or where to look to see if I do have multiple

Tried re numbering devices and too did get devices responding to different commands from other device ID’s

Have tried enabling the ‘Link’ button before discovery, but no, that does not work to help, with dicovery. It does though work to link the Harmony Hub.

These are the small `echo dot ‘flat Alexa devices Model RS03QR with device software 641575220. I see references to Gen 1 or Gen 2 Dot’s, not sure which these will be, though suspect Gen 1

What is my next step to get discovery working again, it only seemed to stop after updating the jar to get the Link button to allow Harmony Hub discovery
