• I have tried reproducing this issue in Chrome and it could not be reproduced there

• I have tried reproducing this issue in ungoogled-chromium with a new and empty profile using --user-data-dir command line argument and it could not be reproduced there

Description

Video streaming and commenting works, but everything else, like following creators, claiming bits seems to get blocked by twitch

How to Reproduce?

(Un-)Following creators

1. Import twitch login cookies to the browser
2. Go to a creator's twitch site you don't follow and try to follow it, or vice versa

---

Claiming channel points

1. Import twitch login cookies to the browser
2. Go to a live stream and wait for a channel points chest appearing in chat
3. Try to claim the channel points

Actual behaviour

For (un)following:
The button gets changed to what you'd expect (goes from "Follow" to "♡" for trying to follow, or vice versa for trying to unfollow), and changes back immediately.

For claiming channel points:
The button which you'd click to claim the points transforms to a red button with the alt-text "Error claiming bonus"

Expected behaviour

To be able to use the functionality twitch.tv provides.

Relevant log output

Logging the network activity of the tab while trying out shows that all responses of the tab have a status code of 200 OK. Only hint I could find is a response from https://assets.twitch.tv/assets/errors-77fdfaad954ba5e86bb7.js upon trying to claim the channel points, as shown in the video.

Additional context

This seems to be related to issues #2676 and #3223 where people also had problems logging in to twitch. I also had issues with logging in, that's why I imported cookies manually, though I can't remember exactly what the problems were, as it was a few months back now.

Streaming videos, using the web player and navigating the website itself does work.
