Stopped working since update

[Ogilvie75]

I was prompted to update and so am on the latest Mac (Intel) version of 2.2

However, ever since Minimserver pops a startup error of: UPnP multicast group 239.255.255.250 is not aaccessible [sic] and I'm not able to do anything else. Nothing else has changed on my router/computer. I have tried restarts, delete and re-installs but nothing works.

I have also downloaded alternative serving software (eg Linn Kazoo Server) which is able to stream without issue but I would prefer Minimserver.

I am running MacOS 12.7.6, Minimserver points to a music folder on an external drive and I stream to a streamer on the same network.

I'm a bit stumped and not sophisticated enough to sort this out through networking, but this was all working fine in the minutes before I hit update so I can only think the new version has introduced a bug or needs me to change something.
