What changed? --> only "Disable Devialet Air"

Disregard. I found out the culprit. I have been traveling and when I do I set my laptop's firewall to block any incoming connection, which it seems the devialet app is trying to make a direct connection back from the devialet to the devialet app. So, on the Mac I first disabled the firewall and things worked. Oddly enough, Macs have the firewall disabled by default which is why I had not noticed the problem. So once I figured it was the problem I added an exception to the firewall to allow the devialet Air app to receive incoming connections.
