Failed to load resource: Error 403

Hi,
I’m getting the below error message in my browser console for my website homepage.

“Failed to load resource: the server responded with a status of 403 ()”

I’m using Contact Form 7 and reCaptcha V2. However, I’m having this issue only in “Home Page”. The Contact Us page also has the same type of Contact Form with reCaptcha V2. But, it’s working fine. I’ve disabled all other external plugins and checked.

Any idea how I can fix this?

Thanks.
