[Solved] Sim2h_server failed to launch (AddrInUse)

Technical Discussion App Development
#1

When I try to launch sim2h_server in nix-shell environment, I get the following error:

sim2h_server
THREAD PANIC PanicInfo {
payload: Any,
message: Some(
    called `Result::unwrap()` on an `Err` value: Os { code: 98, kind: AddrInUse, message: "Address already in use" },
),
location: Location {
    file: "src/libcore/result.rs",
    line: 1187,
    col: 5,
},
}

Which address is used by sim2h_server?

#2

By default, sim2h_server binds to localhost:9000. Is there a sim2h_server already running perhaps?

#3

Thanks for the port.

I was trying too many things at the same time.
