How to make a 301 redirect from HTTPS to HTTP without a certificate?

Question

Nginx

Good afternoon.
Previously, there was a certificate on the domain, there was a redirect from http to https. Currently there is no SSL certificate. Is it possible to somehow redirect from HTTPS to HTTP using NGINX without it?

Answer 1

You can't do it without a certificate. If there is no certificate, get a free one, for example, via https://letsencrypt.org/

Answer 2

the task is not solved in principle, neither by means of nginx, nor by any others. a redirect instruction is issued by the server in response to an https request, which cannot be processed without a server certificate. eudj1n
's advice is good advice. let's encrypt has proven to be quite good.

Answer 3

No way. SSL handshake happens at a level below.
