Hi Abhishek,

I am sorry to hear about this problem.

Thе error indicates that the server closed the connection before sending a complete response. This is the first time we see such an error and for that reason, I cannot suggest an immediate solution. I'm afraid that the available information is not sufficient to diagnose the issue either. Can you share more details regarding the scenario?

Can you attach a Trace Listener to the application? I hope our code will log more details about the error.

• Trace listener for .NET Framework - How to: Create and Initialize Trace Listeners - .NET Framework | Microsoft Learn
• Trace listener for .NET - How to troubleshoot errors in ASP.NET Core projects - Telerik Reporting

If the problem persists, please send me a runnable project we may use to observe the problem locally. If you are hesitant to send your project here, you can open a ticket and provide the details there.

Looking forward to your next reply.

Regards,
Ivet
