HttpIOException: Die Antwort wurde vorzeitig beendet ⇐ C#

[Anonymous]

Wir haben unsere .NET Framework-Anwendung auf .NET Core 8.0 migriert. Unser System, das einwandfrei mit HttpWebRequest von .NET Framework funktionierte, erhält beim Wechsel von .NET Core zum HttpClient einen Fehler, wie in der folgenden Ablaufverfolgung gezeigt.
Client: Windows Server – .NET Core 8.0
Server: Linux Java

Code: Select all

An error occurred while sending the request.

System.Net.Http.HttpRequestException: An error occurred while sending the request.
