I recently installed a SSL certificate for my website following the instructions provided by certbot for apache server, ubuntu 16.04 (xenial). Everything went well and the certificate was installed successfully as per this website. I have revealed my real domain for the purpose of a better understanding.
However, when I run the results here, I have the following errors:
- HTTPS not forced
- Self Signed Certificate
- Domain Matching
I have 3 files under /etc/apache2/sites-available/ namely 000-default.conf, 000-default-le-ssl.conf and default-ssl.conf. As instructed by this website, I tried to add the things to my 000-default.conf in order to force HTTPS, but my site still shows "Not Secure". I am a little hesitant to make any changes to the other files present there as I am a newbie to these modifications.
Question: How and where exactly shall make the changes? Any suggestions would be useful.
