Laravel Websockets Apache2 ReverseProxy setup - laravel

Question

Problem
I am trying to setup a live environment with laravel websockets library behind an apache server.
The Websocket server is running on port 6001 (unreachable from outside).
The Apache VHost is configured for ws.example.com
I cannot get the Apache to proxy the wss:// requests correctly.
The request to wss://ws.example.com/request/path?protocol=7&client=js&version=5.1.1&flash=false fails.
(Error during WebSocket handshake: Invalid status line)
I think there is a problem with my vhost configuration. Am I missing something? Any advice is appreciated.
vhost configuration
<VirtualHost *:443>
ServerName ws.example.com
ServerAlias www.ws.example.com.com
DocumentRoot /srv/vhost/example.com/domains/ws.example.com/public_html
ErrorLog /var/log/virtualmin/ws.example.com_error_log
CustomLog /var/log/virtualmin/ws.example.com_access_log combined
ScriptAlias /cgi-bin/ /srv/vhost/example.com/domains/ws.example.com/cgi-bin/
DirectoryIndex index.php index.html
RewriteEngine on
ProxyRequests off
ProxyVia on
RewriteCond %{HTTP:Connection} Upgrade [NC]
RewriteCond %{HTTP:Upgrade} websocket [NC]
RewriteRule /(.*) ws://localhost:6001/$1 [P,L]
ProxyPass /request/path http://localhost:6001/request/path
ProxyPassReverse /request/path http://localhost:6001/request/path
SSLCertificateFile /etc/letsencrypt/path/ws.example.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/path/ws.example.com/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>

Answer 1

Create a subdomain for websockets. Then edit your virtualhost configs (Apache 2.4) as below. Use pusher-php-server 5.0.3
<VirtualHost *:443>
ServerAdmin admin#example.com
ServerName socket.website.com
<Proxy *>
Require all granted
Allow from all
</Proxy>
SSLEngine on
SSLProxyEngine on
SSLProxyVerify none
SSLProxyCheckPeerCN off
SSLProxyCheckPeerName off
SSLProxyCheckPeerExpire off
RewriteEngine on
RewriteCond %{HTTP:Upgrade} =websocket [NC]
RewriteRule .* wss://127.0.0.1:6001%{REQUEST_URI} [P]
ProxyPass / ws://127.0.0.1:6001
ProxyPassReverse / ws://127.0.0.1:6001
SSLCertificateFile /etc/letsencrypt/live/socket.website.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/socket.website.com/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>

Answer 2

#max: your rewrite rules were the key, also applies when the proxy just forwards the unencrypted traffic and apache is handling ssl to the outside, replacing wss with ws then - after one day of fiddling its finally working!
