Hello, My first post on here, so here goes:
I have a working Ubuntu 16.04 server set up with a few apache virtual hosts, hosting a few sites for me and my mates. I use webmin to manage it normally. I want to use letsencrypt, so I followed this tutorial: https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-16-04
All the sites are WordPress and users are CHrooted to their home directories so when they FTP in they can’t mess with any other stuff. When I change the wordpress URL to https instead on https I get and error that says:
"Secure Connection Failed
An error occurred during a connection to www.mydomain.net SSL received a record that exceeded the maximum permissible length. Error code: SSL_ERROR_RX_RECORD_TOO_LONG
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified."
I’m pretty sure that my Apache SSL module is installed and working, port 443 is open on my firewall too. A port scan confirms this.
I can see a couple .pem files in etc/letsencrypt/keys but have no idea where to start to understand why it’s not working.
After it didn’t work with the first how to guide above, I tried this method: https://certbot.eff.org/#ubuntuxenial-apache
Same error when tying to view SSL pages.
Any help would be much appreciated.
