    You need then to allow google recaptcha URLs. Something like that:

     

    if {!([HTTP::header exists "Content-Security-Policy"])} {
       HTTP::header insert Content-Security-Policy "default-src 'self'; script-src 'self' https://www.google.com/recaptcha/ https://www.gstatic.com/recaptcha/; style-src 'self'; font-src 'self'; img-src 'self'; frame-src 'self' https://www.google.com/recaptcha/ https://recaptcha.google.com/recaptcha/; upgrade-insecure-requests"
}

    What exact captcha are you referring to?

    What is the security headers configuration you've implemented?

        You didn't mention what kind of captcha you are using (recaptcha, hcaptcha, self made captcha ...). If this is an external service (hCaptcha, reCaptcha) you will have to tweak you rules a little bit.
