Can No Longer Log In To Twitch

Kraggy

Just logged out of Twitch after being logged in for a long time, trying to log back in I now get this error:

"Your browser is not currently supported. Please use a recommended browser or learn more here."

Anyone know why they're blocking Vivaldi now?

[edit]

The "learn more here" link in that message is this:

@Kraggy I don’t know what version you are on, but you can spoof any version you might need in vivaldi://settings/network/.

Kraggy

I'm on 7.0.3495.18.

The 'brand' is the default Google Chrome, so how does Twitch know I'm not using a "supported browser"?

I don't know what you're suggesting me to do by changing these settings, I've never been to this setting set before. How would I know what I "need" here?

Any idea WHY Twitch considers Vivaldi a non-legit browser in any case?

@Kraggy Twitch doesn’t know you’re using Vivaldi, it thinks you’re using an outdated version of Chrome stable. Chrome is on 131 while Vivaldi is on 130. Spoofing the 131 version through network settings would be the remedy, but when I tried it just now it didn’t work. What will work is opening Twitch, visiting the network conditions tab in your developer tools and inputting a custom user agent, then reloading. This is the current user agent for Chrome on Windows:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36

You might find it easier to install a user agent switcher extension from the Chrome web store instead.

I don't think this is the case here. I had no problems just now signing in to Twitch with Vivaldi 6.9 (Chr.128). Even tried with 6.0 (Chr.112).

Even if a site says a browser is "unsupported" doesn't necessarily mean it won't work. They just say that to cover their back in case of security stuff etc. The older it gets, the more likely stuff will break, obviously.

And there is no way for a site to know you're running Vivaldi. Vivaldi identifies as Chrome for all sites. So they're not "blocking Vivaldi" and they have zero reason to do so.

So my guess is an extension, probably some adblockers or privacy-related ones that disable certain browser functionality that the site tests for. Could be blocking Service Workers, could be blocking File System API or Storage etc etc. So disable all extensions, clear cache, restart the browser.

It could also be the built-in Vivaldi blocker doing it, so disabling that would be the first thing to do in case it's enabled.

Please try the troubleshooting steps, including testing in a clean profile and disabling adblocking/extensions:

On a side note, I often have the "outdated browser" problem on any site that uses Cloudflare for protection. This is because I block Service Workers, and CF tests for that, as all modern browsers support them.

@Pathduck Would be a good explanation. I don’t have a Twitch account to test it. What bothers me more is that Vivaldi can’t fool webpages when changing the version number in settings, while it’s successful from the devtools. Something appears to be broken there.

Yeah I think the UA Brand Masking is not working well any more, if it ever did... it was never meant to override the User-Agent header though or hide being Vivaldi. All it was meant for was to change the Sec-CH-UA header which is Chromium-specific and broke some sites if the brand was set to Vivaldi. And only the brand, not the browser version.

I consider it more of an "experiment" like many of Vivaldi's more obscure features. Would be nice if it could be fleshed out and made into a proper UA switcher though.

If I want to test UA headers I enable Modheader with my custom headers including all the Sec-ch ones blanked out. Not that it would help much when sites use JS to get the window.navigator values though...

I was able to login at twitch.tv / 7.0.3495.18 Win 23H2

Are you sure that you do not use a "privacy" extension which switches to a very old outdated user-agent an this gets detected?

Kraggy

I don't have any extensions I'd call 'privacy' but I do use adBlock and uOrigin (which I see could be referred to as 'privacy' enhancers) .. I had disabled both on the Twitch domain a long time ago so presumed they'd not be a problem.

As a test I disabled all my addons and was able to log in to Twitch so clearly one of them is the culprit, so I just have to enable on by one till the log in breaks.

Thanks for asking that, because I thought disabling the blockers would mean they're not implicated I didn't try disabling them rather than configuring them not to activate on the Twitch domain.

Kraggy

So I'm now totally bemused .. I turned off all my addons then reenabled them one by one until all were back on and the Twitch login failure hasn't happened again!

No idea what happened but I guess PCs are like that .. thanks again for the replies which at least prompted me to poke around until the problem 'disappeared'.

I also have an infinite loading / black screen (i can log in tho and it work in privacy window)

Since yesterday I've been having the same problem.

I can log in with a private window but not with a regular one. I've disabled all extensions, no privacy blocker enabled and deleted the cache and cookies and it's still not working

Wanted to add that using a new profile did work. What setting in my profile could be breaking anything?

DoctorG

@metroid112 Any message when you can not login?
Do you use in Windows a security tool?

In your old profile try

Remove and readd extensions
Perhaps some extension installation is broken
In Settings → Privacy → Website Permissions
Remove excepetions
Reset Global to Default Permissions
Restart.

@DoctorG

The only message I get is this:

I've deleted every extension from the browser, and set my privacy settings to default, and deleted any website permissions to default too.

I dont have any antivirus software besides the default Windows Defender (running Windows 11). Though I assume if it was a Windows thing it would be affected in the private tab or the new profile too.

Had a look at the source, the message seems to be triggered by some kind of "integrity" failure; was not able to quickly figure out where that test was done.

yngve

A colleague had a closer look at the Twitch source, and the problem may be caused by a problem with the Widevine DRM component (which might cause problems with the integrity check for the module), perhaps also HDMI/DP/DVI cable connection issues.

Go to vivaldi://components and make sure the Widevine component is up to date, once it is, you should restart the browser (on at least one OS the updated component is not used until after a restart).

metroid112

I checked the component but it seems to be up to date in my case:

There's definitely something up with my profile I think.

One thing to try is to clean cookies and other data for Twitch.

Another is to copy one modified prefs at a time over to a test profile (or standalone install) to see if you can isolate the issue.

After a few days it seems to have been solved by itself.
