External broken link recaptcha

Hi everybody!

I’m running WebCEO site audit and I get the next issue:

Page Access Issues:
Broken link (1)
https://www.google.com/recaptcha/api/fallback………. (etc)
Found on: many pages

The issue affects to all the pages where I use Contact Form 7 with recaptcha, which are lots.

I’ve been said that the url for displaying the reCAPTCHA is: https://www.google.com/recaptcha/api.js

How could I change it?

My site is a WordPress site (Version 4.6.1), with the plugin Contact Form 7 (Version 4.5.1)

Thank you in advance for your help.

Best regards
