[Answered ]-Recaptcha Django cms – captcha validation take more than a minute

I don’t believe it…

I hope I can help people with this, because I just think is crazyness…

Disable IPV6 was the solution!

Here how to do it with ubuntu 12.04:

add these lines to sysctl.conf file

#disable ipv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

then run ‘sudo sysctl -p’ or reboot.
