Unblocked website but Google Recaptcha does not appear

Hi, I am having trouble of unblocking a website’s recaptcha. My configuration is blocked all the websites with a firewall rule and Allowed only some webpages to access for certain group (address list), so far all the webpages allowed works fine without a problem until this one came out, the google recaptcha would not come out, I already allowed all google recaptcha IP, but still does not appear.
The webpage is: https://servicios.set.gov.py/eset-publico/perfilPublicoContribIService.do

Is there any solution? Apprecitated!

You could use ruc24.com.py/consult , thats what i am using.
