XF 1.4 ReCAPTCHA connection timed out

This error started showing up a couple of weeks ago, now I'm getting the error dozens of times a day:

ReCAPTCHA connection error: Unable to Connect to tcp://api-verify.recaptcha.net:80. Error #110: Connection timed out
I have not made any changes to firewall, configuration or whatsoever. All OUTPUT is allowed, and all INPUT on 80/tcp is allowed in IPtables.

Any ideas why this might be happening consistently?

If it's happening consistently then it could indicate a network or connection issue between your server and the recaptcha server.

You would typically need to ask your host or sysadmin to investigate.
