:point_right: Endpoints issue


I was on holiday and everything was down for a week. Started everything up and now my KEF LS50 Wireless II and Sonos Five do not work in roon. Aurender and Hifiberry/RPI4 work fine. The KEF and Sonos work fine with there own app but not anymore with roon.

Roon sees the endpoints and start playing (no sound) but after a few seconds i get “unable to play” and it stops

Hello @Luc_Vandevyver

I think the next step here is to enable some diagnostics on your account so our technical staff can get some more insight into what’s going on here.

However, before I enable this feature, I’d like to ask for your help ensuring we gather the right information.

First, can you please reproduce the issue once more and note the time at which the error occurs. Then respond here with that time, and I’ll make sure we review the diagnostics related to that timestamp.

Hi, I tried today again with the same issue. 26 may at 8:05 > 8:15

TheKEF still does not work, however for some reason the Sonos now does work again.

Hey @Luc_Vandevyver,

We’ve activated diagnostics and reviewed that timestamp. It shows a series of connectivity issues, including timeouts and the device losing several endpoints.

Can you please provide more information about your network setup? We have seen users have a better experience in the past if they change their Router’s DNS servers from the ISP provided ones to Cloudflare DNS, Quad9 or Google DNS. Can you please give this a try and let us know if it helps?

My provider is Telenet in Belgium. I cannot change the DNS of the router or the dhcp. I can only change the DNS on the Roon core. And that is now changed to 1.1.1.1. In the meantime I discovered that it is only a Live Radio problem No problem with Qobuz or local flies. None of the radio stations in “My Live Radio” work. All others do work in Roon. see photo

The stations not working in Roon are working fine with the Kef and Sonos apps.

Tested again on 2nd Jun from 7:45 to 8:15 with same results

Hey @Luc_Vandevyver,

Thanks for the update! A fresh Roon Server diagnostic report shows us the problem isn’t DNS, it’s a TCP connection block to port 80 on icecast.vrtcdn.be (VRT’s streaming server, which hosts Radio 2, Studio Brussel, etc.).

Telenet is blocking outbound TCP connections on port 80 to icecast.vrtcdn.be. Every radio stream attempt fails with Error Connecting to icecast.vrtcdn.be:8, Roon tries ICY, HTTP, and HTTPS methods, all on port 80, and all are refused.

What you can try:

  1. VPN on the Roon Server machine: A VPN installed on your Server host will route traffic around Telenet's block.
  2. Check if icecast.vrtcdn.be has HTTPS/443 streams VRT has been migrating streams. You could manually add the stations using newer HTTPS URLs (e.g. https://icecast.vrtcdn.be/stubru.aac) in Roon's "Add Station" dialog.
  3. Contact Telenet: Ask them why outbound TCP to icecast.vrtcdn.be:80 is being blocked. It may be unintentional and fixable on their end.
  4. Test from another device on the same network: Open http://icecast.vrtcdn.be/stubru.aac in a browser on the same machine as Roon. If it also fails, this confirms the Telenet block definitively.
Thank you! 🙏

Thanks for your investigation. Why should they do that. It’s been working for years. Don’t understand. Anyway, I have some more info. Could not update Rooncore with error downloading. Rebooted the router from provider and update worked and now the Radiostations work again. So the problem was my router to start with. ■■■■ happens with IT. Its always something…THank for the assistance and keep up the good work.

I am a happy lifetimer

Hi @Luc_Vandevyver,

Thanks for the update, and for narrowing it down to the router. If anything changes again, please let us know and we can take another look. Glad to hear it’s working again, and we’ll go ahead and close this one out. Enjoy the music! :musical_notes:
