[severity:It's more difficult to complete my work]
Hello, we are migrating our Xamarin app to MAUI.

In Xamarin we were used to check the availability of our APIs with CrossConnectivity.Current.IsRemoteReachable("https://xxxxxxxxxxxxxx", 33233))

We see this IsRemoteReachable is not actually present as method of the CrossConnectivity, how can we now check in MAUI?

Thank you!

Can create a helper class and use sockets to ping the host like the original method:

public async Task<bool> IsRemoteReachable(string host, int port = 80, int msTimeout = 5000)
{
	if (string.IsNullOrEmpty(host))
		throw new ArgumentNullException("host");

	host = host
		.Replace("http://www.", string.Empty, StringComparison.CurrentCultureIgnoreCase)
		.Replace("http://", string.Empty, StringComparison.CurrentCultureIgnoreCase)
		.Replace("https://www.", string.Empty, StringComparison.CurrentCultureIgnoreCase)
		.Replace("https://", string.Empty, StringComparison.CurrentCultureIgnoreCase);

	return await Task.Run(() =>
	{
		try
		{
			var clientDone = new ManualResetEvent(false);
			var reachable = false;
			var hostEntry = new DnsEndPoint(host, port);
			using (var socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp))
			{
				var socketEventArg = new SocketAsyncEventArgs { RemoteEndPoint = hostEntry };
				socketEventArg.Completed += (s, e) =>
				{
					reachable = e.SocketError == SocketError.Success;

					clientDone.Set();
				};

				clientDone.Reset();

				socket.ConnectAsync(socketEventArg);

				clientDone.WaitOne(msTimeout);

				return reachable;
			}
		}
		catch (Exception ex)
		{
			Debug.WriteLine("Unable to reach: " + host + " Error: " + ex);
			return false;
		}
	});
}
