[Resolvido] Unable to parse data from service response

Hello, I have a staging site here link oculto
and I correctly generated a wpml key, but when I add it in the backend in Commercial, I get this message "Unable to parse data from service response"

Solution: this most often happens if there is a Firewall on your site or server blocks access to essential endpoints. You can ask your hosting provider to make sure the IPs from this ticket are whitelisted: https://wpml.org/forums/topic/cannot-register-wpml-license-key-unable-to-parse-data-from-service-response/#post-14035759
