1) After following the steps in this video (https://www.youtube.com/watch?v=GPcznB74GPs) on how to install free SSL using ZeroSSL, I encounter a problem that shows 404 Not Found in my website. Although i enter https://(my_domain_name).com manually in the URL, it still doesn't show the HTTPS. In my C-Panel>SSL STATUS>I can see that my domain is validated (with a green lock beside it)
2) At the end of the tutorial in the video, there is some codes that need to be placed inside .htaccess file (in the public_html root directory) in order to automatically change the URL into https:// URL. (Tutorial code as below)
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
I have previously installed magento 2 and the .htaccess have its own similar code. (Magento 2 code as below)
RewriteEngine on
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule .* index.php [L]
1) There are others that encounter the same problem and provide their solutions like rename my file /.well-known/acme-challenge/(FILE NAME.txt) to /.well-known/acme-challenge/(FILE NAME), however, mine does not have a .txt to begin with. There is another video that says to rename the pictures/source which had http in it to https by inspecting the page>console (It will shows mixed-content warning). However, mine does not show any mixed content warning.
2) When i tried to replace and/or add the above magento 2 code with the tutorial code, I got too_many_redirect error.
My website/domain name is www.aevuswebs.com
Go to database of your Magento & search for the table Core_config_data with in that table look for the rows with the current URL details of your website that is without SSL.
Update the detail & add 's' into both secured & unsecured base_url's something like below
http://www.example.com/ -> https://www.example.com/
Try to reload your website it will load.
