HTTPS no redirection to the captive portal

[lezidev]

Hello !

My problem is simple to understand but difficult to handle. I set up a captive portal and choose HTTPS to get its traffic on my portal but it only works with HTTP.

I have rode several posts about it but some are old so my question is : Can I make the captive portal redirect correctly?

When I type http, or IP it redirects to the captive portal (test with 8.8.8.8 among others). But when it's https, I'm okay if it doesn't allow the certificate, etc. but is it possible to get at least the certificate error ?
And the user could go on.
