[Can I use an external URL as a portal?]

I am trying to use the evil portal module to open an external URL, but a message always appears saying that the connection is not secure and the web does not open.

I tried adding this script to index.php:

<script>

window.location.href = "https://google.com";

</script>

And also tried this:

<form action="https://www.google.com">"

I don't know what can happen, whenever I want to open an external URL from the captive portal, the security error appears, as if I couldn't use https, but my website does have https.

Normal portals do work for me, the problem is when putting an external url.

I have never created captive portals and my failure is probably silly, if anyone knows what can happen, I would really appreciate it.

(sorry for my english, i use a translator 😅)
