For some reason I cannot use port 443, can I use another port

Install & Config
1

My company does not allow port 443, so I want use another port, for example 9443 port.
How do I configure?

2

Just set apache2/nginx to listen to ssl 9443 port

and change port in the
/etc/jitsi/meet/your-address.com-config.js like

bosh: ‘//your-address.com:9443/http-bind’

Yesterday I installed the server and changed port, it works.
