It's not the cache. It appears when I access from other computers.
When i tried to install the SSL certificate and I got to this part of the tutorial:
There were 3 options to select. I selected 000-default.conf and it didn't work, probably the DNS was still updating so I tried later and selected the same 000-default.conf and it worked. I selected the secure option to have all connections through HTTPS and I runned the command:
sed -i "s|DocumentRoot /var/www/html|DocumentRoot /srv/rutorrent/home/|g" /etc/apache2/sites-enabled/000-default-le-ssl.conf && service apache2 restart
Then I checked: the SSL was working but the non-ssl address was showing the Apache Default Page.
Is there any config file I could check if something went wrong the first time I tried?
