    Hello, This kind of question has been asked several times, and no solution found for me.
    I have installed apache2 on a raspberry pi, everything is working (mail, php,mysql, phpbb) exept port 443 : it is closed :
    • sudo nmap 192.168.2.91 -> cannot see port 443
    • telnet 127.0.0.1 443 on my server : telnet: Unable to connect to remote host: Connection refused
    • openssl s_client -connect localhost:443 Connexion refused errno=111
    I did :
    generate certificates with openssl
    edit 000-default-ssl.conf and default-ssl.conf to adapt my conf.
    sudo a2enmod ssl
    sudo service apache2 restart

    In /etc/apache2/ports.conf, I can read
    Listen 80
    <IfModule ssl_module.c>
    Listen 443
    </IfModule>


    I cannot understand why my 443 port is closed !

    Thank you Blank for helping.
    I cannot check everything explained in your above links :
    • sudo vi /etc/network/interfaces gives no answer, no error
    • sudo iptables-save does not give what I wrote in /etc/network/iptables ( I did sudo iptables-restore /etc/network/iptables)
    It's like other config files are used. In my box, ports 443 and 80 are opened and redirected to the raspberrypi. I can reach the raspberry from Tor browser and my noip domain name.
    Error with https locally or from the internet !
    What I did :
    • back up files and database
    • format sd card and install Raspbian Stretch Lite image
    • update / upgrade
    • Add a user and delete pi user
    • install apache2 and telnet (openssl is installed with apache2)
    • install and configure proftpd
    • install and configure php7.1
    • install and configure mariadb
    • install and configure exim4
    • install and configure phpmy admin
    • create my database and restore the backup
    • upload files via filezilla
    • check my phpbb forum is Ok
    • create certificates with help of https://the-bionic-cyclist.co.uk/2017/03/22/setup-ssl-on-a-raspberry-pi-in-2-minutes/
    • follow your link : http://simonthepiman.com/how_to_setup_your_pi_for_the_internet.php
    Same problem : https : //192.168.2. myraspberryip /index.html : error / unsecure connexion
    or, with Tor browser : https:// mydomain.fr /index.html : error / unsecure connexion
    (I've added spaces in above links because this forum rejects those lines ... and I cannot post my reply)
    • sudo vi /etc/network/interfaces gives no answer, no error
    • sudo iptables-save does not give what I wrote in /etc/network/iptables ( I did sudo iptables-restore /etc/network/iptables)
    So, what I did before answering today :
    install apache2, php7.1, mariadb phpmyadmim, exim4, proftpd, and setup ssl on my Archlinux system. Then iptables
    Same problem : https :// localhost / index.html : error / unsecure connexion

    Can I check https locally or is it only working from the outside (I can simulate "outside" with Tor Browser)
    I'm missing something somewhere : are the pages I used outdated today or are they more probably not complete (missing informations)

    I can answer first question : yes, https can work locally. I try to generate a new local certificate and configure apache for it ...

    About iptables : right now, iptables are not really important as my raspberry is not in the DMZ of my internet box. Only ports 80 and 443 are redirected to my pi3 !
    Am I wrong about this ?

    Ok, it does work locally after accepting my own certificate.
    i'll try from the outside next week end.
