apache - Proxy not redirecting

Question

I have the following Apache config file. When someone types in http://mywebsite.com it is not redirecting them to https. Why?

<VirtualHost *:80>
    ProxyPreserveHost On
    ProxyPass "/" "http://10.0.1.123/"
    ProxyPassReverse "/" "http://10.0.1.123/"
    ServerName www.mywebsite.com
    ServerAlias mywebsite.com
    RewriteEngine on
    RewriteCond %{SERVER_NAME} =mywebsite.com
    RewriteCond %{SERVER_NAME} =www.mywebsite.com
    RewriteRule ^ https://mywebsite.com%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

<VirtualHost *:443>
    SSLEngine on
    SSLProxyEngine on
    ProxyPreserveHost On
    ProxyPass "/" "http://10.0.1.123:80/"
    ProxyPassReverse "/" "http://10.0.1.123:80/"
    ServerName www.mywebsite.com
    ServerAlias mywebsite.com
    ServerAdmin [email protected]
    Include /etc/letsencrypt/options-ssl-apache.conf
    SSLCertificateFile /etc/letsencrypt/live/www.mywebsite.com/fullchain.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/www.mywebsite.com/privkey.pem
</VirtualHost>

Answer 1

<VirtualHost *:80>
    ... 
    ProxyPass "/" "http://10.0.1.123/"
    ...
    RewriteRule ^ https://mywebsite.com%{REQUEST_URI} [END,NE,R=permanent]

The ProxyPass is telling Apache to work as reverse proxy and forward the request to the real server. The RewriteRule instead is telling Apache to answer the request itself with a redirect to the HTTPS version of the site. Obviously it cannot do both at the same time, so there is a conflict. Please remove Proxy* rules and keep only the Rewrite* rules on port 80.
