SnmpSharpNet.SnmpException: 'Request has reached maximum retries.'

Question

I was researching SNMPv3 for an internship and I got this code from snmpsharp.net (I couldn't show all of the code stackoverflow wouldn't let me)

using System;
using System.Net;
using SnmpSharpNet;
namespace SharpGetV3
{
    class MainClass
    {
       public static void Main(string[] args)
       {
           IpAddress ipa = new IpAddress("192.168.1.5");
           UdpTarget target = new UdpTarget((IPAddress)ipa);
           SecureAgentParameters param = new SecureAgentParameters();
           if (!target.Discovery(param))
           {
                Console.WriteLine("Discovery failed. Unable to continue...");
                target.Close();
                return;
           }

I couldn't get past the line

if(!target.Discoverey(param))

It gives me the error SnmpSharpNet.SnmpException: 'Request has reached maximum retries.'.What could be the cause of this?I could run SNMPv2 get requests just fine.Apologies if I can't answer your questions I'm still trying to understand how all this works.
