Issues with playing and adding some live radio stations

Sitar · December 13, 2025, 9:48am

Hello,

unfortunately I’m experiencing issues with some live radio stations for a couple of months now and need support to solve this problem.

For instance the following stations did work perfectly fine the last years without any issues, but do not work anymore and trying the play them I get the error massage “unable to play this station. Its address may have changed, or it may be temporarily unavailable.” :

Deutschlandradio: Deutschlandfunk
Deutschlandradio: Deutschlandfunk Kultur
Deutschlandradio: Deutschlandfunk Nova
Bayerischer Rundfunk: BR-Klassik

and there are several more which I tried and do not work.

Others just work fine and respond immediately. Examples:
Klassik Radio
Klassik Radio Lounge
Linn Classical, Linn Radio, Linn Jazz

The URLs of the station not working in Roon, just work fine in a browser. And adding URLs for these stations also do not work in the "my live radio " section. Example:

https://st01.sslstream.dlf.de/dlf/01/high/aac/stream.aac

Error message: “roon could not find a radio station at this URL”

For other stations, like Klassik Radio, adding the station just works fine: “https://stream.klassikradio.de/live/mp3-128/stream.klassikradio.de/”

Other radio stations like “Octave Radio”, take a very long time before they start. Octave Radio starts 2.5 minutes after pressing play. But at least it eventually starts. Interestingly trying to add the exact same url, which roon live radio is using “https://octaverecords.out.airtime.pro/octaverecords_a” give the error “roon could not find a radio station at this URL”. In a browser the station starts instantly.

Okay, sorry for the long poste and thanks a lot in advance for support and advice to solve the issue.

Hello @Sitar , I have no problems playing these stations. I wonder if your DNS cache is corrupted?

Can you reboot whichever device holds the cache?

If that doesn’t work, I’ll move this to Support

Sitar · December 13, 2025, 11:14am

Hi Brian,

well, that was also something I suspected. I’m using ROCK and to test if the problem could be related to DNS, I’ve configured ROCK to use 1.1.1.1 directly on web interface instead of my Home Network DNS server.

Sometimes, if I reboot ROCK the stations work. Then after a while they fail again. Usually 1 day. Is there a DNS cache on ROCK which can be configured?

Sitar · December 13, 2025, 11:17am

Hi Brian,

just additional information. I’m not a network expert, but at a first glance the following report does not suggest a caching issue, when I use 1.1.1.1 directly in ROCK, right?

Ok, moving to where the experts live.

Any other info about your setup will be useful.

vadim · December 15, 2025, 12:09pm

Hello @Sitar

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.

Sitar · December 15, 2025, 8:51pm

Hello Vadim,

thanks for your help.

Yes, I’ve rebooted ROCK and after reboot live radio for the mentioned stations works fine. Usually it takes some hours until the issue occurs again. So, as soon as I notice it, I will send the information.

benjamin · December 15, 2025, 10:43pm

Hi @Sitar,

If you’re able to temporarily test changing your rotuer’s DNS server as well, that would be helpful in troubleshooting.

We’ll be on standby for your reply and timestamp (date,time, name of track playing) thank you!

Sitar · December 17, 2025, 7:33am

Hi Benjamin,

okay, I rebooted ROCK on 12/15 in the evening. The Radio Station worked. For the test I
tried the station “Deutschlandradio: Deutschlandfunk”. Next morning it still worked. But then in the evening same problem and it didn’t start anymore. In the evening I also tried the other stations from Deutschlandradio, like “nova” and “kutur”. Although I didn’t started them after reboot before, they didn’t work in the evening. So, probably an indication that it is no caching issue?
Between the first request to start the station until the station starts playing there are a lot of error messages related to “http” requests, which roon tries to make “https” requests. But it eventually starts.

Btw, the official urls from deutschlandfunk are https urls (Deutschlandfunk Livestream: Links für Webradios und Player). Updating the urls in the roon live radio, which are still “http” might help.

Here are the time stamps of the log files:

Hi Benjamin,

just rebooted ROCK and now the radio station works again. So, same behavior as observed already.

Unfortunately, for some reason Roon won’t accept or play those particular https streams.

Hello @Sitar !

Thanks for sharing the logs. This helps clarify what’s happening.

From the log, Roon is able to connect to the Deutschlandfunk stream and initiate playback but the server does not return a valid live radio response. Because of this Roon immediately abandons the URL and tries the fallback streams (MP3 and lower-bitrate AAC) which fail in the same way.

There are no network, DNS, or codec errors shown in the log. Instead, this behavior indicates that the broadcaster’s streaming infrastructure (CDN) is intermittently delivering the stream without the required radio metadata/headers. When that happens, browsers can still play the audio, but Roon cannot validate it as a live radio source and stops playback.

This also explains why the station may work earlier in the day and then fail later - different CDN endpoints can behave differently over time.

Unfortunately this is controlled by the broadcaster’s streaming setup and is outside of Roon’s control. Using an alternative MP3 stream or a different station URL is the best workaround at the moment.

Regards.

Hi Alex,

thanks for the support and analysis.

But does the CDN topic explain the behavior that after a ROCK reboot the radio stream works and after a roughly a day it does not work anymore? What does the reboot change related to the CDN issue?

The other question is, what would be the problem description for the radio station support to be able to fix this issue? Of course it is not clear if they would care. But I would like to give it a try.

Thanks.

Hey @Sitar,

A reboot:

Flushes DNS resolution
Resets HTTP connection pools
Forces new CDN edge selection
Rebuilds redirect/token paths

It does not fix the root cause , it just temporarily lands you on a working CDN node. This is squarely on Deutschlandradio / ARD CDN configuration, not your network or ROCK.

You could mention: Some CDN edge nodes do not return valid ICY headers for live streams, causing strict clients to fail.

Hi Benjamin,

Okay, thanks for the explanation.

alex_h · December 18, 2025, 5:17pm

You’re welcome @Sitar .
