Recaptcha fails even if I get the green tick

[Ignacio Sanz]

Hi.

Since a few time ago, I'm getting errors in pages using recaptcha. I pass the recaptcha test (the green mark appears) but when I press OK, Submit, Send or equivalent button I get a "wrong captcha" message. I have to do it several times (maybe 10) before passing it.

It happens with: Opera beta, Opera (stable) for Android, Firefox (stable) for PC, Firefox (stable) for Android.

I suspect it's due to IPv6 captchas in IPv4 or something like that, since my ISP (Orange Spain) switched my IP from IPv4 to IPv6 recently. Can you fix this?

Some pages failing (there are more pages)

- Moonbit.co.in. (Bitcoin faucet)

- 20minutos.es (Spanish online newspaper)

- FileJoker.net (File locker)

Responses like these are not welcome:

- Ask your ISP for a IPv4: Paying for a static IPv4 is not an option.

- Use a VPN: Even more expensive.

- Ask the pages for using IPv6: There are too many pages affected.
