Can't see MinimServer in network player(s) after upgrading to DSM 7

[sk8ir]

Hi Simon, many thanks for the quick response!

Yes, it was the Synology firewall that I turned off completely.

It's so odd - I do think I've tried pretty much everything. I can see the config page just fine, and it says "Running", I just can't see MinimServer as a source on any of my clients/endpoints (sorry, not sure of correct terminology!) any more, and MinimWatch 2 doesn't seem to be able to see it either.

All the permissions on the NAS seem to be fine.

I've had a good delve into the router's settings and can't see anything relating to IGMP Snooping.

I did a bit of a search online for anything relating to my specific router and found this: https://en.avm.de/service/knowledge-base...onnection/
which I think I've interpreted as meaning that the router doesn't do IGMP Snooping by default, and it's not configurable (they talk about disabling it on other devices but not on the router itself).
