I'm getting the same error, also on 2.5.11+matrix.1, but on ArchLinux.

If I can help by trying something or providing logs, let me know!

I switched Twitch to two-factor authentication yesterday. When using the Twitch addon right after that I was asked to renew my oauth token, which I did. Right before that everything worked fine, but since then I get the exact same error.

I undid 2FA, but the error stayed.

Did you guys enter an OAuth Token in the Private API Credentials section of the Login menu (at the very bottom)? I get this error message when I enter an incorrect token there (probably also when it expired)

Notably, it is NOT the same as the OAuth Token at the top of the same menu. See here https://github.com/anxdpanic/plugin.video.twitch/issues/461#issuecomment-552670340 how to obtain this second token from the Twitch webpage.

Thanks for the reminder. Apparently, switching to 2FA caused my oauth-token in settings.xml ("Private API Credentials") to become invalid. I had to grab it from my twitch website cookie again, copied it into settings.xml and now everything works perfectly again as before. I'm sure if I had done that after enabling 2FA it would have fixed the issue as well.

Thank you, that really was the problem in my case! The whole setup is really unintuitive, though :( The process of getting the first OAuth Token is complicated enough, but the one for the Private API Credentials section? Without your help I would have never known what to do...

FYI: For who is setting this up via the config file (.kodi/userdata/addon_data/plugin.video.twitch/settings.xml):

• The first OAuth Token goes into the oauth_token setting (remove default="true")
• The OAuth Client ID from the Private API Credentials section (kinme78...) goes into the private_oauth_clientid setting
• The OAuth Token from the Private API Credentials section (extracted from the website as explained here) goes into the private_oauth_token setting

Again, thanks for your help!

I'll agree that documentation, UI and probably also error handling for this could be better (if someone has the time and is willing to do it is another story).

As for the process itself, I'm not sure it can be improved by a lot. This private OAuth token and the APIs it's used for are not part of the official Twitch API, so there's no straight forward way to obtain it. Maybe it would be possible to implement a full login feature, where you enter your username+password (+2FA) and it fetches the token for you. But I feel like this would be a significant amount of work and comes with its own set of problems (like would you actually want to give your password to the addon?)
