I have only used Apache HTML on my backend and implemented my app using HTML/PHP requests so far. Now I want to implement a socket connection. For this, I am currently trying to set up the socket module on my Apache web server. I tried these steps. Reverse Proxy. However, after adding ProxyPass on the VirtualHost :443, I can no longer access my HTML pages.
503 Service Unavailable - The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Is it possible to still access the HTML/PHP pages despite the socket module? Do i have to create a new VirtualHost with a different Port, e.g. the Websocket Port but how can i make the handshake? My apache2/sites-available/conf looks like this:
<VirtualHost *:80>
ServerName ***
<IfModule mod_ssl.c>
Redirect / https://***
</IfModule>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/***
