Why can I not pass captcha with antidetect browser?

[Servant of the Creed]

Trying to create some accounts on my own using antidetect + local proxy.
No matter which antidetect browser I use, accessing the page takes forever and even if I solve captcha correctly, it does not pass.

Why is this happening and how can I get over it?

What antidetector you use? maybe thats the problem or else the site so change that too

CAPTCHA fails likely due to low-trust proxies or unnatural browser fingerprints. Use high-quality residential IPs, human-like behavior, and realistic fingerprints for better results.

I think it's your proxies. They must be of poor quality.

In your case, the issue probably comes down to sketchy IP reputation and wonky browser fingerprinting. Local proxies usually have IPs that are already on some blacklist or just look shady so bot protection kicks in before you even get to the CAPTCHA. Even if you do get past it stuff like mismatched timezones, weird WebGL or Canvas data or super robotic mouse movements can still give you away. You should try using a solid residential or mobile 4G proxy (not the cheap junk), make sure all your browser fingerprints match the proxy’s location and move your mouse and click around like a real person would. Also you can try Pixelscan or CreepJS. They're great for spotting what’s blowing your cover

I tested a proxy from thesocialproxy.com, also mostly Hidemyacc but I also tried AdsPower and Dolphin Anti. Even though I use the same proxy, I keep getting errors with WebRTC, Mobile Connect (this is sometimes good, sometimes bad) and blacklist (which I assume happens because of the VPN?). I did buy a mobile proxy, but with rotating IP, is that a problem?

So I do need to make sure that timezone of proxy + timezone of browser match, right?
Recommendations for good proxies are appreciated, altho I kinda see that this requires special relationships because everything that is promoted eventually gets used?

Thank you for Pixelscan and CreepJS, I will look into it.

I bought a mobile proxy from thesocialproxy.com. Only rented for 2 days for testing purposes.
I always a scenario like in the picture (sometimes WebRTC is ok).

Thank you. I need to check the subject of browser fingerprints. I have seen that I can change them, but I know nothing about them.

Hidemyacc, dophin, adspower. Also tried now gologin.

Judging by your screenshot, looks like you're using Hidemyacc, right? Every time a Hidemyacc profile opens, websites often detect the IP as coming from IPFighter. In my opinion, the captcha failures are mostly due to low-quality proxies, especially datacenter ones. Google almost always throws a captcha when you're using those You might want to switch to a better proxy provider.

1. Use Better Proxies
Residential/Mobile Proxies (e.g., BrightData, Smartproxy) work best.
Avoid datacenter IPs (OVH, AWS, Google Cloud) unless they’re very clean.
Test your proxy at IPQS to check if it’s flagged.

2. Improve Antidetect Settings
Enable realistic fingerprints (match OS, browser version, GPU, etc.).
Disable WebRTC leaks (a common giveaway).
Use timezone matching (proxy location = browser timezone).

3. Solve CAPTCHA Properly
Use manual solving (not automated tools like 2Captcha).
Move the mouse naturally when solving.
Wait a few seconds before submitting.

4. Warm Up the IP & Browser
Before creating an account, browse Reddit naturally for a few minutes.
Visit a few posts, upvote, scroll—make it look human.

5. Clear CAPTCHA Cookies
Some antidetect browsers retain CAPTCHA tokens, causing loops.
Try a fresh profile or clear cookies before each attempt.

6. Try a Different Antidetect Browser
Some work better than others. Popular options:
Dolphin Anty (good for Reddit)
Gologin (strong fingerprinting)
Incognition (lightweight but effective)

It’s likely your proxy is flagged or your fingerprint looks fake. Even if you solve the captcha, Reddit or other sites can still block you based on those signals. Try using high quality residential proxies and double check your timezone, language, and device settings in the antidetect browser.

 

[Proxy4Free]

Your proxy may be marked. It is recommended to change to another one. Static residential proxy or mobile proxy can be used.

Make sure your fingerprints are good.

You can run some tests

Test 1 - try to pass through those captchas without a proxy --> if you can, the problem is the proxy
Test 2 - try to download another antidetect browser --> try to pass using this alternative browser

It could be related to browser fingerprints, or the proxy IP quality might be poor.

The issue is likely with your proxies or unnatural fingerprints.
Try switching to residential or mobile proxies and set up a more realistic fingerprint — this should help bypass captchas and speed up loading.

Which static residential proxy do you suggest?
