Erhalte "Authentifizierung fehlgeschlagen, weil die entfernte Partei den Transportstrom geschlossen hat." während der API-Aufruf an UPS Tracking-Rest-Service

Question

Ich bin UPS Tracking-API in meiner asp.net mvc 5 Anwendung implementieren. Ich habe unten die Methode erstellt.

Das funktioniert gut, wenn ich es von meinem lokalen Rechner aus anrufe. Aber als ich meine Anwendung auf dem AWS-Server bereitgestellt habe, gibt es immer wieder Ausnahmen. Was könnte der Grund sein, ich stecke jetzt fest.

System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Authentication failed because the remote party has closed the transport stream.

Versuchen Sie, diese irgendwo im Code hinzufügen, bevor der Aufruf der Webservice zu machen:

    System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Ssl3 
             | System.Net.SecurityProtocolType.Tls 
             | System.Net.SecurityProtocolType.Tls11 
             | System.Net.SecurityProtocolType.Tls12;
