Unable to Live Stream on Twitch

I have 1gigabit FTTP and have been trying to live stream on Twitch but I'm encountering an issue.

The stream connects to Twitch for exactly 10 seconds with good bitrate, then immediatley cuts out to 0kbps. It periodically regains connection only to immedaitely cut out again.

I'm using ethernet and have tried putting my Hub5 into Modem Mode, disabling the firewall and using CloudFlare DNS but none of these fixed the problem.

My only thought is that Virgin are detecting that I'm streaming and cutting off the connection? Do Virgin do this? I can't find anything saying they don't support streaming on the website and the speeds are more than good enough.

  • I had an engineer round who fitted an attenuator to the line which seems to have fixed the problem. Apparently the upstream signal was too low frequency and the high bandwidth usage of streaming was causing the connection to become unstable.

    Since the engineer visit, I've not had anymore problems with dropouts.

  • I think you're confused. You don't stream to Twitch using a browser.

    Anyway, I'm using OBS, I can see in the OBS logs there are RTMP errors.

    20:25:32.741: WriteN, RTMP send error 10054 (4097 bytes)
    20:25:32.741: WriteN, RTMP send error 10038 (79 bytes)
    20:25:32.741: WriteN, RTMP send error 10038 (42 bytes)

    This indicates a network error when streaming.

      This issue has been going on for years apparently. Have you had a look at the official OBS forums?

      The general consensus is that this is some sort of hardware/software issue and not necessarily an issue with your internet connection.

      One forum post suggests it's because of a mismatch in audio sampling rates somewhere in the chain. Have you made sure all audio is set to 48Khz?

      Some posts suggest its due to the Network Interface Card sending malformed packets.

      One post suggests chaning the MTU on his NIC fixed his issue.

      I would have a look around the OBS forums search for "RTMP send error" - there's a lot of suggestions on there.

      What is your packet loss like, have you tried setting up a Broadband Quality Monitor?

      Sounds like they're throttling you. Happened to a friend of mine and he had to stop streaming his tournaments. Vm are a joke when it comes to streaming

    Hi JamesHCooper

    Have you tried a different browser? If not try a different browser.

    Also try logging out of Twitch using your current browser and then completely wipe the cache and cookies, restart the browser, and then log back into Twitch again. 

    VM don't use traffic management - see the section More about our speeds - traffic management on
