Oppo 203 & HEO connection issues

I could not reproduce the StringIndexOutOfBoundsException with your tagFormat setting but I could reproduce it by putting two consecutive $ characters in the setting. I will fix this problem in the next MinimServer update.

As you have changed your tagFormat setting to work around this problem, it should not be related to the discovery issues you are seeing.

Your Synology NAS is hard wired to the router via the switch. Your iMac is (I presume) connected wirelessly via the WAP. This suggests that the UPnP discovery problem is related to the wireless connection. Can you try using an Ethernet connection from your iMac to the switch to see whether this makes a difference?
