Kodi 21 / pvr.nextpvr 21.3.2.1 – Live TV stops after 30–60 minutes, HTTP range error

[Rad]

Hello,
I am experiencing recurring Live TV playback interruptions when using the NextPVR PVR client in Kodi.

My setup:

• NextPVR Server: 7.1.1.260616
  
• NextPVR running in Docker on a Synology NAS
  
• Kodi 21 with pvr.nextpvr 21.3.2.1
  
• IPTV channels configured in NextPVR
  
• Kodi and NextPVR are connected over the local network
  

The problem:
Live TV playback works normally for approximately 30–60 minutes, then suddenly stops and Kodi returns to the channel guide.
The issue occurs with different IPTV sources, not just one channel. Playback through the NextPVR web player appears stable.

Tests already performed:
I tested different NextPVR Live TV buffer settings:

Buffer size       Approximate playback duration

20 minutes      28–30 minutes
60 minutes      40 minutes
120 minutes    55–60 minutes

I also tested the Kodi NextPVR client's Real Time and Timeshift playback methods.
For the latest test:

• Live TV method: Timeshift
  
• Direct Streams: Disabled
  
• NextPVR Live TV buffer: 120 minutes
  
• Kodi
  
  Code:

  advancedsettings.xml
  :
  
  Code:

  curllowspeedtime=60

Unfortunately, the problem still occurs.

Relevant log messages:
Kodi reports:

Code:

CVideoPlayerAudio::Process - stream stalled

followed by:

Code:

Reconnect, (re)try 1

and:

Code:

Failed: Requested range was not delivered by the server (33)

The NextPVR logs show messages including:

Code:

stream@2 got zero bytes client disconnected Live stream expired without 15 second renewal.

After the stream disconnects, Kodi attempts to reconnect using an HTTP byte-range request, but playback cannot recover.

My questions:

1. Is this a known issue with the Kodi NextPVR client or NextPVR's Live TV streaming?
   
2. Could the HTTP range/reconnect behavior be responsible for the playback stopping?
   
3. Is there a recommended fix or workaround?
   

I have attached sanitized Kodi and NextPVR logs from the latest playback failure. Sensitive URLs, credentials, network addresses and identifiers have been redacted.
Any help would be greatly appreciated.
Thank you!

A bit of cleanup for the future.

- Kodi problems should be in the Kodi sub-forum here https://forums.nextpvr.com/forumdisplay.php?fid=13
- As documented I need Kodi debug logs, the default are useless.
- You probably need to set the timezone in Docker to log the correct time.

The reason that streaming failed is here

Code:

2026-10-08 12:29:22.621 [DEBUG][90] Got request [[KODI_LAN_IP]]: /service (channel.transcode.lease) 2026-10-08 12:29:29.637 [DEBUG][32] Got request [[KODI_LAN_IP]]: /service (channel.transcode.lease) 2026-10-08 12:29:36.644 [DEBUG][98] Got request [[KODI_LAN_IP]]: /service (channel.transcode.lease) ... 2026-10-08 12:30:01.832 [ERROR][12] Live stream expired without 15 second renewal. (handle:210004)

The lease expires but Kodi sends the lease every 7 seconds and your Kodi log level or the redactions doesn't show any logging to help figure out what might be going on to block the API calls.

Code:

2026-10-08 14:21:27.519 T:4237 error <general>: GetDirectory - Error getting /storage/.kodi/userdata/addon_data/plugin.video.themoviedb.helper/timer_report/ 2026-10-08 14:30:00.657 T:4227 info <general>: CVideoPlayerAudio::Process - stream stalled 2026-10-08 14:30:21.372 T:4221 error <general>: CCurlFile::CReadState::FillBuffer - (0xa847c678) Failed: Failure when receiving data from the peer(56)

It is not generic CE problem, I use it all the time.
