I noticed months and months ago some CSGO matches hosted on Twitch TV would fail to load. "Network Error 2000" among others. Twitch is a youtube competitor when it comes to gaming. (Youtube also owned by google). I can open these URLS for CSGO matches in literally any other browser w/o issue. There's nothing really in the way of articles on this or people with "fixes". They're straight up trying to fuck a competitor by breaking their own shit (the chrome browser) and it's obvious.
I do use ghostery and ublock origin among other stuff like https only. I can uninstall all that in chrome and google products still somehow break shit. I'm telling ya. It's not a coincidence. I'm using linux, mac, windows, and a chromebook for guests in this house. Everything works fine in regards to twitch until... I install a google product. My google products will work about 50% of the time when it comes to loading twitch.
It can be completely uninstalled on a fresh chrome install. No logins. Chrome will still break twitch streams like 50% of the time w/o anything. Sometimes I restart the machines it works fine. When they've been running a day or two they break twitch.
It may also be caused on your end by an extension that blocks stuff. Do you use uMatrix or Ghostery, anything like that?
