What modules are are you using with apache?
Don't forget to open port 8443.

[peterremote1980]

I am using ProxyPass module, i confirm 8443 is opened.

[edwinbrowwn]

ProxyPass is just an argument in the config. Make sure you have the respective apache modules installed to support headers and such.
Here is the command to install the mod_prox module.
apt install -y build-essential
apt install -y libapache2-mod-proxy-html libxml2-dev
a2enmod
proxy proxy_ajp proxy_http rewrite deflate headers proxy_connect proxy_html
You will then see a list of modules you can install. Then restart after you have what you need.

Take a look at that; you're missing a few config directives that are causing your websockets to be treated like normal HTTP requests. (Unexpected response code: 200 means that your websocket request is getting a normal web page back.)

[sr229]

From first glance your configuration does not support HTTP upgrades, which the websocket needs.

You might want to use rewrite to proxy depending on http upgrade.

RewriteEngine On
RewriteCond %{HTTP:Upgrade} =websocket
RewriteRule /(.*) ws://192.168.10.124:8443/$1 [P,QSA,L]
RewriteCond %{HTTP:Upgrade} !=websocket
RewriteRule /(.*) http://192.168.10.124:8443/$1 [P,QSA,L]
