I don't see that error on my end, maybe if I restart the miner, but I did this morning. Probably a gradual change. Sending M3U8 was disabled in a different project the other day (but they also changed from PubSub to Hermes) so def something there.

Haven't looked into how that's handled here, yet..

As pointed out in this comment, it looks like Twitch has finally started dropping the old PubSub API. I can confirm that the web client (at least for my user) no longer attempts to connect to it. Instead, it connects the to newer Hermes API. It shouldn't be too hard to implement a Hermes client, based on my earlier look into it. I'll try and have something implemented in the next few days.
