We use this for Apache and a SockJS app behind Apache. Apache is doing WebSocket proxy automatically, but you have to rewrite the scheme to ws otherwise it fallbacks to XHR. But only if the connection is a WebSocket handshake. Adding the following will fix your problem :) (note: change the localhost:3000 accordingly to your own backend url.

RewriteEngine on
RewriteCond %{HTTP:UPGRADE} ^websocket$ [NC]
RewriteCond %{HTTP:CONNECTION} Upgrade [NC]
RewriteRule .* ws://localhost:3000%{REQUEST_URI} [P]
