Problem connecting to core from android roon remote

There’s a long thread on the topic already:

Android app having trouble finding Linux Core

Ever since I installed the build 233 version of the Android Roon app (a build 234 one hasn’t made it through the pipeline yet), my phone hasn’t been able to find the Core (which is now at build 234, but this was also the case with build 233); I’m unsure about whether the issue is related to the app upgrade or the core upgrade since they happened pretty much simultaneously, but I may remember having been able to connect to a build 233 RoonServer from a pre-233 Android app. Build 233 and 234 Mac…

I had the same problem with different Android versions and an Ubuntu core for a long time until I turned off IGMP snooping on the Netgear managed switch that sits in between the wifi AP and the core machine.
