I have the Twitch 5 extension installed on chrome. Never had issues, even with my 10mbps ADSL. This is not a app or extension issue. Regardless, will still give it a shot, during these difficult times.
Just to recap, not sure if my problem got lost in translation... I have 100mbps fibre. Since last week tuesday, I have been unable to stream twitch, getting 2000:network error. I can bypass this by using HordVPN. The problem is, I now have 1/2 the speed as well, during peak time where pings go up to 30+- and download speeds @ 50mbps, which should still be fine for twitch streaming, but I suspect the packet drops are the issue for my 2000:Network errors.
