Hey,
So you’re telling, you can’t connect with firefox twitch but youtube works. And if make a hotspot on your pc and connect your phone to it, you can connect to twitch?
What does the error message say? Can you provide more detail?
Can you assemble a list of many links that are not working? (I want to point out, that it is twitch.tv and twitch.com is just a redirect to twitch.tv. Like @Strit already pouinted that out Downgrade from Manjaro 20.2.1 to Manjaro 20.2 - #4 by Strit )
