Answer 1

I got the same error an tried a couple of suggestions, but nothing realy worked.

So I logged my network traffic and analyzed it. What it shows is that mid connection the servers changed from ipv4 to ipv6 and I remembered reading somewhere that recaptcha has a problem working on ipv6.

So I changed @fsockopen($host, [...] to @fsockopen(gethostbyname($host), [...] and recaptcha worked again.
