FWIW
My win10 is on chrome 124, and i don't use VPN or proxy.
I've tested this PR (as a source based python run), and it solves for trupornolabs, riperam, marinetracker, devil-torrents, 52BT, which were indexers that were giving me issues previoulsy.
Also tested against most of the other cloudflare protected indexers that were previously working for me, and they continue to work with this PR.
Some indexers however continue to fail, leporno still returns the invalid cookies error, and ext-torrents which now fails on ext.to but works for the other 2 alternate domains.

But after each solve there remains a chrome subtask that starts to spin up to 15% CPU and I have to manually kill them off.
Should I test using this PR win10 exe?
[edit] Oh wait, there isn't one.

Another thing that I've noticed is that in the user-agent headless replacement:

                self.execute_cdp_cmd(
                    "Network.setUserAgentOverride",
                    {
                        "userAgent": self.execute_script(
                            "return navigator.userAgent"
                        ).replace("Headless", "")
                    },
                )

I don't know why but If I hardcode the user-agent using the exact that my computer has like this:

user_agent = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36"
options.add_argument(f"--user-agent={user_agent}")

it bypasses cloudflare, but if i put this to make it automatically like you have it on line 533 from src/undetected_chromedriver/__init__.py it does not work.

So an alternative could be to setup a driver only to get the user agent:

def get_user_agent(driver):
   return driver.execute_script("return navigator.userAgent;").replace("Headless", "")

And then pass the user-agent to the definitive driver

PD: I only can tell you what I've discovered to see if we can go through the solution cuz I'm having troubles to get the project installed/set up 😅

Hello. I just wanted to let you know that this didnt bypass the challenge on arab-torrents.net, showing the same internal server error. I am not using VPN, proxies and I dont have a datacenter IP. Let me know if you need any info to troubleshoot this further.

I didnt actually use this branch, it worked fine after I switched to it. Thanks

@garfield69 yea this seems to be an issue with Chrome v124. You can revert to v123 in the mean time if it's easier - #1161

Alternatively, build your own binaries, which will use Chromium v123:

pip install -r requirements.txt
pip install pyinstaller
cd src
python build_package.py

@m33ts4k0z were you doing this on Windows?

@m33ts4k0z were you doing this on Windows?

Yes on a Windows 11 VM on Unraid but it did work in the end. I updated my first post here with the cause.

Alternatively, build your own binaries, which will use Chromium v123:

python src/build_package.py

Oh cool, did not know I could build on windows.
Built successfully and tested. Much better, no left over chrome tasks chewing CPU anymore :-)

@juanfrilla sorry for the delay in replying, been busy and only got to a few quick ones on my phone.

I'll have a look at the UA idea when I next get a chance, thanks.

Assuming you're following the run from source instructions, what issue are you having? https://github.com/FlareSolverr/FlareSolverr#from-source-code

@ilike2burnthing my main problem is that i cannot install Xvfb on MacOS

Tried XQuartz?

Tried XQuartz?

yessir now the project is set up, let's see what I can fix

What exactly is left to do on this to get it merge? I tried to guess with the comments here and some different issues but I can't get the current status of this. It seems to be stale for quite some time, so what's needed?

Unfortunately, currently this only works on Windows, and the looping challenges return if using proxies or VPNs.

Well, I made my own implementation of this "new tab" idea and I was able to make it work with every website I could (ext.to, www3.yggtorrent.cool, dodi-repacks.site, hd-torrents.me/login.php, nhentai.net) on my Linux system using a VPN / socks5 proxy and also with my container image on my own remote Linux server, which was blocked by cloudflare too.
Unfortunately I can't test on Windows, so if someone can test that and report back please do.

That's working 95% of the time on Windows for me, even with a proxy, but failing 95% of the time on Docker. Usual error:

Error: Error solving the challenge. 'NoneType' object has no attribute 'startswith'

Seems it's related to get_correct_window and trying to get driver.current_url. Adding some extra logging shows that the URL is returned as None. Adding some additional sleeps then shows the correct URL, but I'm still getting challenge loops or crashed.

That's working 95% of the time on Windows for me, even with a proxy, but failing 95% of the time on Docker.

When you say it fails on Docker, is it still on Windows or Linux?

I got this error on Linux while doing my implementation, but have not been able to replicate it since. For the looping challenges, it seems to be a timing issue. Playing with the timer values can make it work in some cases, but it's not easy to know what works for everyone since it seems to take network latency into account. For example, if I use a proxy close to my location, it works 100% of the time with the sites I listed earlier, but if I use a proxy very far from me, it works 50% of the time.
Can you try to increase the timers to something like 6, 8 or more?

Linux.

I'll play around with timings again (I did a bunch yesterday), see if I can get something that works both on my Docker and Windows.

Linux.

Strange then. I'm able to solve the challenges of all sites I try on my Debian and Fedora systems with different VPNs/Proxies with and without Docker involved.
Can you share an example of one of your tests with debug enabled?

Here's an example with dodi-repacks.site using the docker image I shared previously:

replacing the image of the dockerfile for this:
python:3.11-slim-bullseye works perfectly locally on MacOS M2 with and without proxies (tested for my website "https://www.icj-cij.org/sites/default/files/case-related/187/187-20231215-ord-01-00-en.pdf", I can get the cf_clearance cookie

I tested as well on a centOS server with the previous image (python:3.11-slim-bookworm) and it doesnt work

I believe @21hsmw you are aware of this one - although reading through the comments on this discussion, I did see some attempts were made to fix sessions. I can create a session but when I try to destroy it, it errors and then the task queue grows (doesn't complete).

@21hsmw looks like the Docker version is being detected, whereas running from source on Windows is working fine. Basically the challenge is found, checkbox is clicked, but challenge just reloads. I tried an apt-get update and upgrade, and restarting the container, but no luck.

Alternatively, build your own binaries, which will use Chromium v123:

pip install -r requirements.txt
pip install pyinstaller

python build_package.py

Want to compare dockerized vs native performance; running locally however gives me:

$ python -u src/flaresolverr.py 
Traceback (most recent call last):

Any pointers?

either downgrade python to 3.11 or install legacy-cgi with pip, i guess

"It was removed in Python 3.13 after being deprecated in Python 3.11.
....
The last version of Python that provided the cgi module was Python 3.12"

Flaresolverr full work for me on VM ubuntu with Google chrome (no docker)
Maybe install google chrome in your docker image and I think work :)

thanks, finally i put alexfozor's image and it works mais 21hsmw will probably do an update so that it works with its version

Hello, on my side alexfozor's image doesn't works I guess it's due to the fact I have an intel processor on my unraid station meaning I need 386 version or something like that.

I can confirm that alexfozor/flaresolverr:pr-1300-experimental is working (the v2 does not work) as a workaround for me

Yes, there are currently 2 versions that work. so Alexfozor's image: alexfozor/flaresolverr:pr-1300-experimental

and another called Byparr: ghcr.io/thephaseless/byparr:latest

the current image of @21hsmw does not work. Waiting for an update

My branch has been updated after the recent captcha looping issue.
If you see any change in behavior, please report it to me here.

• Update Chromium to version 133
• Update nodriver to version 0.40
• Fix captcha looping issue

Hi, does your solution work with non-interactive cloudflare challenges? Even with your latest changes, I get "Challenge not detected!" when trying to access a page

You'll need to give an example URL for anyone to be able to help you.

You'll need to give an example URL for anyone to be able to help you.

Yea, sorry, here is a URL.
It has a non-interactive challenge, and when trying to bypass I get that challenge is not found.
@21hsmw is your solution supposed to work with those kinds of turnstiles?

FlareSolverr doesn't currently work with this type of integrated check, just whole page challenges.

@21hsmw updating Chrome to v135 on Windows is causing problems:

• launches but then almost immediately returns the error Error solving the challenge. cannot unpack non-iterable NoneType object
• reverting to v134 works
• working on Docker (didn't test updating Chromium though)

Would it be possible to set the chrome version to download/run via ENV variables? This is more convenient for docker users who pull from the repo instead of rebuild images.

@21hsmw Any chance that you can release docker images for arm64 arch?

v3.3.22 - Windows and Linux binaries available, as is an updated flaresolverr/flaresolverr Docker image.
