Description Of Issue

Samsung SM-T510 (Tab A) Tablet got an update today and will no longer connect to the core (most of the time - if I walk away and leave it for half an hour it might connect… once). I have removed the app, rebooted the tablet and reinstalled the app with the same result. When I contacted Samsung their response was to wait until the app was updated by the vendor (NO HELP). The update, unfortunately, cannot be removed. There is no problem connecting to my Wi-Fi or to the Internet on the tablet. All of my other Windows PCs (there are 3) have no trouble connecting to the Roon core. Can you assist? Am I missing something?

If you haven’t already tried this …

Periodically unable to connect to Roon Core - [Solved - Netgear Orbi Router issue - Solved by Enabling IGMP Proxying]

I unchecked the box “Disable IGMP Proxying”. Disable IGMP Proxying The IGMP Proxying function lets a LAN PC to receive the multicast traffic it is interested in from the Internet. You can click this check box to disable the function if you do not need it. I believe the intended effect was to enable the IGMP proxy function from the internet to the LAN side. I have no idea how this affected muticast traffic from one host to another on the LAN side but my laptop is now able to consistently find…

I’d look at firewall settings on your core. It is possible the update changed the way the tablet identifies itself to the firewall.

Thanks for the suggestions.

I unchecked the “Disable IGMP Proxying” and continued to experience the same problem.

I think if it were a firewall issue, it would never connect. Instead it sometimes connects but if it does, it takes forever to do so.

I was hoping Roon support would chime in. I imagine others are experiencing a similar problem with Samsung devices that get this update.

Hello @Robert_Broder, and thanks for your report! When you’re on the “waiting for your core” screen, could you please tap the “help” option and try entering 255.255.255.255 as the core’s IP when prompted? Let me know if that works!

Hello Nuwriy, Thanks for your response.

That worked! The tablet connected immediately.

Is this a permanent fix or will I have to enter the IP address each time?

Thanks again.

Hello @Robert_Broder, I’d recommend entering the IP for now but this is an item our QA team is aware of and hopes to make changes in this area in the future. Thanks for your patience while we investigate the issue.
