Consistent indefinite hanging on remote connection

[eighty4]

git2-rs is blocking on RemoteConnection over cafe WiFi but works fine on my home network. Sometimes this happens with git when I'm on a public WiFi so I checked and git will pull or clone with SSH over the same network. Is there a configuration piece missing I overlooked? I see RemoteCallacks has proxy config and cert checks in addition to the credentials callback I'm using.

The program works great when the connection doesn't hang indefinitely. Here's an excerpt of where it hangs and here is the complete example.

fn pull() {
    let mut remote_connection =
        remote.connect_auth(Direction::Fetch, Some(remote_auth_callbacks()), None)?;
}

fn remote_auth_callbacks<'a>() -> RemoteCallbacks<'a> {
    let mut remote_callbacks = git2::RemoteCallbacks::new();
    remote_callbacks
        .credentials(|_, username, _| git2::Cred::ssh_key_from_agent(username.unwrap()));
    remote_callbacks
}

Thank you for the great examples in this crate. It helped me put together my work smoothly!
