sub domain configuration for network encoder

[milehighkaraoke]

@DanielnetoDotCom
can you help me with this? I have been trying to get this to work all day but can not seem to find the correct combination.

VirtualHost *:81>
ServerName encoder.mhktube.com
ServerAlias www.encoder.mhktube.com

RewriteEngine On
RewriteRule ^/(.*) http://10.10.10.100:80/$1 [P,L]

RewriteCond %{SERVER_NAME} =encoder.mhktube.com [OR]
RewriteCond %{SERVER_NAME} =www.encoder.mhktube.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]

<VirtualHost *:8443>
ServerName encoder.mhktube.com
ServerAlias www.encoder.mhktube.com

SSLEngine on
SSLCertificateFile /etc/letsencrypt/live/mhktube.com/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/mhktube.com/privkey.pem

RewriteEngine On
RewriteRule ^/(.*) https://10.10.10.100:443/$1 [P,L]  # Remove the extra space before the "/"

I get the 443 forbidden
https://encoder.mhktube.com

`<VirtualHost *:443>

ServerName encoder.mhktube.com
ServerAlias www.encoder.mhktube.com`

turn 8443 to 443, and then probably it will not tell fobidden

443 is being used on front end along with 80
I am trying to redirect encoder.mhktube.com at the front end and point it to apache on backend

I have absolutely no idea what I am doing but I am digging in and giving it a go. Spent close to 40 hrs with Gemini and Chat GPT that ended with a blown up Apache2 lol
