使用 SSL 将 Apache 设置为 VPS 上的正向代理

Question

I have a React app with express server listening port 3000 deployed on VPS (which has some IP 123.123.123.123) with Apache. Also I have SSL setup. The problem I have is that on page refresh/direct path entering I'm getting 404 error. But everything is working fine once I set example.com:3000/page. At the moment I have .htaccess file with this setup:

RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Which redirects to https.

I need forward proxy setup to be done correctly to port 3000.

Any help with this setup will be very helpful as I'm stuck with the development.

Regards,

You will need to setup a reverse proxy on your Apache to redirect traffic on port 443 to port 3000. It can be done by adding the following lines in your Apache config

ProxyPreserveHost On
ProxyPass / http://0.0.0.0:3000/
ProxyPassReverse / http://0.0.0.0:3000/
