how can I bind to my own domain? TcpListener::bind("own_domain")

[julialember]

Recently I got my own domain (let's say "example.online") and I had a desire to write a server part for my application with
let listener = TcpListener::bind("example.online").await.unwrap();
but instead of bind it gives me an error:
called Result::unwrap()on anErr value: Os { code: 49, kind: AddrNotAvailable, message: "Can't assign requested address" }
Is it possible to somehow fix this? I have a hosting and a DNS server, the сite itself works fine if connect to it on the Internet, but for some reason the binding does not work

You do not bind to a domain. You can either bind to a specific interface, or to all interfaces. Usually you only have two interfaces: localhost and your internet connection, but if you're connected over both ethernet and wifi you might have three interfaces. Binding to 127.0.0.1 only accepts connections from the local machine. Binding to 0.0.0.0 accepts connections from anywhere. Most likely you should just bind to 0.0.0.0.

but 0.0.0.0 is also a local address, and I need it not to be local. my domain has an ip server too, but I can’t bind to it

Are you trying to prevent connections from localhost? Otherwise I don't understand. If you bind to 0.0.0.0, then that accepts connections from anywhere, local or not.

What do I need to enter in the address bar to get to the port 0.0.0.0 page?

You can enter any IP address or domain that refers to your machine. As long as the port matches, it should work. For example, if you bind to 0.0.0.0:8123, then the local machine can reach it via 127.0.0.1:8123. Similarly, if the server has IP address 192.168.0.17 on the local network, then other machines on the local network can reach it at 192.168.0.17:8123 (unless your router blocks the connection).
