Anybody else having trouble with cloudflare ?

@Calidann I have a similar issue here. Doesn't seem to be much of a problem when I use Google Chrome and create a web app like Crunchyroll, but when I go to it under Vivaldi, it brings up that verification that you are not a bot thing like what you said. I don't know if it's either the DNS, cookies, ad-blocker, ISP, or just a Vivaldi thing. Either way, one needs to come up with something to fix this situation.

Hmmmmm, More details are needed. My impression is that happens after login, right? If so, we can't test directly.
When hearing about such happenings I am now inclined to suspect Client Hints abuse.
In the last couple of desktop snapshots we have added a test capability to change the information that can be used to do such targeting. One of the places I posted info is this forum post . If you could do that kind of testing, particularly changing the brand to "Google Chrome" that would be useful.
BTW, even if this was about Cloudflare, and likely the same system, it might have been better to start a new thread; this one is more than a year old.

The problem was 90 von 100 are the side ( or other on Crunchyroll ) https://www.crunchyroll.com/de/videos/new
are see but at one second the front change to the cloudflare man button check side.
yesterday for many hours are all normally .... but in the video i showing the side make a change and the check has coming. and the rest are the same before .. all sides with crunchyroll..... are now with a check ...
see picture ....( in german )

I have now learned that you should test with the guest mode.
I have now in guest mode the page Crunchyroll.com and /new surfing several times and no interference by Cloudflare get.
strange

@Calidann OK, so this does not sound like the Client Hints scenario, but something in the detection algorithms used by the site or Cloudflare. What that is, I don't know, it could be "random", or it could be triggered by how the site is navigated, or something completely different. I suspect, tough, that they won't fix it until it causes them to lose lots of paying customers.

Just found out about guest mode today. Looks like even in Guest mode site like http://captcha.website (used flor Privacy Pass extension) still cannot pass Cloudflare. Probably at this point just contact Cloudflare to help resolve issue. Upon open the Dev Console I saw this:
-
@Trung0246 5.7.2921.65 Win 11 - I do not see any problems on the mentioned sit with Cloudflare captcha.
Please check Troubleshooting issues.

I have noticed that cloudflare only seems to like chromium browsers. My non-chromium browsers do not get anywhere with it.
-
@DoctorG Looks like I found the root cause: apparently upon checking vivaldi://flags, I checked all modified flags and I saw somehow I disabled "Site Isolation" flag. Probably I somehow forgot to re-enable it back when doing webdev stuff. Revert the flag back to default immediately fixed the problem.
-
I had this cloudflare problem and turns out I was the dumb one that forgot about having my User Agent spoofer set to FireFox But glad I checked the forum and found out why I kept failing the captcha checks from cloudflare.
-
On some domains server-sided Cloudflare protection checks against valid user-agent ids, it something is strange, it blocks or shows captcha.

@JeffTracy, in this case t's a problem with your internet connection, maybe the DNS you use. Try with 9.9.9.9
-
Lately with Cloudflare, I get, "Your browser is out of date!" with Vivaldi. I have the latest version. Faking the user-agent does not work.
The only browser I have (out of 5) that works with Cloudflare is Safari. -
@Streptococcus
Hi, do one need to login to https://www.cloudflare.com/ ?
No issues with the main page and Vivaldi 6.6.3271.55 here.Cheers, mib
EDIT: I create an account, no issues: -
I lately had the "your browser is outdated" issue on a prominent site I'd rather not link here.
Looking in the devtools console I got the following error:
Refused to create a worker from 'blob:https://challenges.cloudflare.com/2d99b550-d3a1-4e50-be94-67396dbfe676' because it violates the following Content Security Policy directive: "worker-src 'none'".
It was then obvious this was caused by my rule in uBO blocking service workers. So I created an exception rule specifically for this domain.
@@||$csp=worker-src 'none',domain=example.com
Blocking SWs will obviously cause a lot of grief on sites, but I'm happy to add exceptions when needed. It should be noted that this block is not default in uBO, it has to be added specifically.
uBO will also block some stuff like:
https://static.cloudflareinsights.com/beacon.min.js/v84a3a4012de94ce1a686ba8c167c359c1696973893317 net::ERR_BLOCKED_BY_CLIENT
So people encountering problems with CF will have to do the necessary digging and do the usual troubleshooting as expected. It's clearly not Vivaldi being "outdated".

Just allowing beacon.min.js has worked with Vivaldi and LibreWolf. It did not work with Pale Moon or SeaMonkey.
