发生异常: CLR/CoAPnet.Exceptions.CoapCommunicationException
“CoAPnet.Exceptions.CoapCommunicationException”类型的异常在 System.Private.CoreLib.dll 中发生，但未在用户代码中进行处理: 'Error while resolving DNS name.'
发现内部异常，有关更多详细信息，请参阅变量窗口中的 $exception。
最里面的异常 System.Net.Sockets.SocketException : 不知道这样的主机。
在 CoAPnet.LowLevelClient.LowLevelCoapClient.d__12.MoveNext() 在 c:\Users\19112\Desktop\github\CoAPnet-master\CoAPnet-master\Source\CoAPnet\LowLevelClient\LowLevelCoapClient.cs 中: 第 118 行

To me it looks like that the DNS name could not be resolved. Maybe the DNS server is not reachable?
