How to permanently redirect?

[Sanat-Teli-V2STech]

I am using nginx proxy manager with TailScale. I want to permanently redirect all my traffic through domain and disable it whoever tries accessing it over http or <TailScale-server-ip>:<application-port>
I have added a redirection host where domain name is <server-ip>:<application-port> and forward domain is sub.my-domain.com, scheme is http and http code is 301
I have also enabled the Preserve path and Block common exploit yet whenever I access it using <server-ip>:<application-port> it is accessible instead of getting 301.

I would appreciate some help, thanks!
