access denied

[tcurdt]

What's the best way to get some more information why this isn't working?
I assume this is because there is no way to obtain an acme cert?
Or would it fall back to self-signed certs?

use tide_acme::{AcmeConfig, TideRustlsExt};

#[async_std::main]
async fn main() -> tide::Result<()> {
    let mut app = tide::new();
    app.at("/").get(|_| async { Ok("Hello TLS") });

    // app.listen("127.0.0.1:8080").await?;

    app.listen(tide_rustls::TlsListener::build().addrs("127.0.0.1:4443").acme(
        AcmeConfig::new()
            .domains(vec!["domain.example".to_string()])
            .contact_email("[email protected]")
            .cache_dir("/Users/foo/tide-acme-cache-dir"),
        )
    ).await?;

    Ok(())
}

$ curl -k https://localhost:4443
curl: (35) error:14004419:SSL routines:CONNECT_CR_SRVR_HELLO:tlsv1 alert access denied

Same here, with a slightly different error:
curl: (35) error:14094419:SSL routines:ssl3_read_bytes:tlsv1 alert access denied
I couldn't figure out what's wrong either so far.
