I'm using EO.WebBroser 23.4.26
For a few days I have no longer been able to access some sites, it seems that cloudfare detects the browser and blocks it even though the captcha is resolved. I also set a useragent before calling the webview.. but nothing to do..
I get stuck on the captcha screen (screenshot: https://app.screencast.com/hbWHV5Fc798zX)

Any suggestions?
Thanks

Hi,

Can you try the latest build and see if it works for you? We tested it here and it seems to work fine.

Thanks!

Hi,
thanks for reply.
I've just tried with latest build, but still not working.

If I try outside the app, accessing from chrome or edge, I'm able to solve the captcha and cloudflare allows me to access to the site...

Can you share a test link? We tested it here with the latest TabbedBrowser sample with an online demo site and it appears to work fine. We can try your link here and see what we can find.

Is there any special steps we need to follow? We open pagesjaunes.fr with our TabbedBrowser sample application (build 2024.0.96.0) and we do not see CloudFlare captcha at all.

We did notice some problem with this site even though the captcha says "verification successful". We will look into it further to see what we can find.

OK thank you.
In my case it never appears "verification successful"... it just keeps in the loop verification state. Same issue with pagesjaunes.fr link.

Dear support,
did you discovered something to bypass the problem? Or have some suggestions I can try?
My app accesses these sites and is currently no longer usable...

We did find a problem with cookies and we are still working on it. This would require code changes on our end so there is nothing you can try on your end at this moment. We will reply here again when we have any more information.

Hi,

We have sent a test build to you through private message. Please download that build and run TabbedBrowser sample application from that build and see if it works with site community.ls-rp.com. We tested it here and it appears to work correctly.

Thanks!

Very strange. I'm receiving a lot of complaints also from users that uses the app...
I could give you teamviewer access, so that you can see that from a regular browser I'm able to access to that websites, not with TabbedBrowser... please let me know...

It seems to be a ban that occurs when you access a cloudflare website several times (my app browses the inner page of the website)..but this ban only occurs if you access with EO.WebBroser... (if I access it from a normal browser, the check is successful).
This is what I see in the TabbedBrowser console... there are some errors and warnings...

Hi,

This is just to let you know that we were able to reproduce this problem in one of our systems. We will continue to work on it and post again when we have any update.

Thanks!
