How to install HTTPS (not HTTP) on localhost on macOS Sequoia?

I tried to install HTTPS on current macOS version 15.5 using this way but with no success.

Is there something I’m missing?

• http://localhost still working
• https://localhost returns ERR_CONNECTION_REFUSED

I can give you all more information you need, below is the way I tried.

1. I have isntalled current brew version 4.5.2

2. brew install mkcert

3. mkcert -install

4. sudo nano /etc/ssl/localhost/localhost.conf

5. I have put there

   [req]
   default_bits = 1024
   distinguished_name = req_distinguished_name
   req_extensions = v3_req
   
   [req_distinguished_name]
   
   [v3_req]
   basicConstraints = CA:FALSE
   keyUsage = nonRepudiation, digitalSignature, keyEncipherment
   subjectAltName = @alt_names
   
   [alt_names]
   DNS.1 = localhost
   

6. sudo openssl genrsa -out /etc/ssl/localhost/localhost.key 2048

7. sudo openssl rsa -in /etc/ssl/localhost/localhost.key -out /etc/ssl/localhost/localhost.key.rsa

8. sudo openssl req -new -key /etc/ssl/localhost/localhost.key.rsa -subj /CN=localhost -out /etc/ssl/localhost/localhost.csr -config /etc/ssl/localhost/localhost.conf

9. sudo openssl x509 -req -extensions v3_req -days 3650 -in /etc/ssl/localhost/localhost.csr -signkey /etc/ssl/localhost/localhost.key.rsa -out /etc/ssl/localhost/localhost.crt -extfile /etc/ssl/localhost/localhost.conf

10. sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain /etc/ssl/localhost/localhost.crt

11. sudo apachectl restart
