Hard to solve browser-captchas: What to do?
Some Browser Captchas may be hard to solve sometimes.
While this article is mainly about Googles reCaptchaV2, the basics of it will also fit on other browser captchas.
Symptoms - how do I recognize hard to solve captchas?:
Instead of a single "I'm not a robot" click captcha like this:
... you may encounter multiple challenges in a row e.g. "Click on all traffic lights", "Click on all cars" or similar:
There is no way to determine the factors which e.g. Google is using to decide which captchas you get 100% but there are some things known to "make these captchas easier to solve".
This article is mostly about the widespread "reCaptchaV2" but it may also apply to other interactive captchas e.g. hCaptcha.
1. Use Google Chrome --> Google prefers users who use their own browser
You can keep using the browser of your choice and use Chrome only for JD! See HERE!
2. Disable your proxy/VPN if you are using one.
If you are using a proxy/VPN in JDownloader, consider using the same via browser (and the opposite way too).
3. Make sure you are logged in into a Google account in the browser you are using to solve browser captchas.
A "real" Google Account which is not only used for captcha solving is better than one which you've just created for the purpose of solving captcha.
4. If you are in a network where a large amount of people are sharing one external IP address e.g. company- or university network, this can also cause hard to solve captchas.
In this case, a private VPN might even be your solution but first you should change your network and test if you get better captchas e.g. via mobile network or with your home IP address (as long as it is not used by a lot of people).
5. If you need to solve a lot of reCaptchaV2 captchas you might want to try a supported paid captcha solver service such as 2captcha.com.
