Port 443 isn't by definition more secure, it is the default port for https (Hyper Text Transport Protocol Secure) trafic (port 80 typically is for http (Hyper Text Transport Protocol) trafic), it also in most cases requires a valid SSL certificate unless you have a self-signed certificate, in which case you can bypass any "insecure site" messages fairly easily.

Try your link explicitly with HTTPS (Example: https://<your-custom-domain-or-IP+port-here>)

Otherwise you may have to set up something like certbot and/or Let's Encrypt and generate a valid SSL certificate to access your CasaOS userpanel. As for how to set that up, I am no expert, unfortunately.

EDIT: Added context.
