Google reCAPTCHA Image Not Showing when using OpenDNS

[Jason Codispoti]

Hi, 

I am currently attempting to troubleshoot an issue with the Goolge reCAPTCHA Image not showing up for a client.... This particular client is using OpenDNS filtering to BLOCK ALL WEBSITES except for the sites that we white-list I suspect that this is why the reCAPTCHA Image is not loading for them. This being said I have not been able to determine what needs to be white-listed in order for the reCAPTCHA Image to load, does anyone one happen to know what I should white-list? 

Thanks!

On the client side, the user's browser has to be able to access

• https://www.google.com/
• https://www.gstatic.com/
  
• https://fonts.gstatic.com/
• https://fonts.googleapis.com/

On the server side, your webserver needs to be able to access

• https://www.google.com/recaptcha/api/siteverify
  

It's important to note though that host whitelists are very difficult to manage. Nobody will notify you if the list of servers changes and it can change at any time.
