BC Server on Azure keeps reporting AspNetCore errors from web clients

(0) ShareShare
ReportReport
Posted on by 15

Hi everyone,

I manage a Dynamics 365 Business Central server hosted on Azure, and I found errors related to AspNetCore errors.

Version installed: Dynamics BC 365 CU04 Spring Update 14.0.35916.0
SQL Server: 2017 Standard 64bit 14.0.2027.2

Due to these errors, the web clients keep disconnecting randomly.
The internet connection on the Azure server is obviously fast, but the error states "Reading the request body timed out due to data arriving too slowly. See MinRequestBodyDataRate". I just don't know what kind of issue it is related to.

The steps I have done in order to solve the problem were these:

  • reinstalled the Web Instance
  • reinstalled the NET Core Library (version 2.1.11) and .NET Framework (version 4.5.2)

Have someone found an error like this?

I paste down here the stack of the error.

Microsoft.AspNetCore.Server.Kestrel
Connection id "0HLRJ4CQAMQD2", Request id "0HLRJ4CQAMQD2:00000002": An unhandled exception was thrown by the application.

    Hi,

    I asked to one of my colleagues, he told me that this means to edit the default web instance code of Dynamics BC.

    I have already installed this version in other server and it did not give such errors.

    I have to make an addition to the previous answer.

    I noticed that the Prod.Client.WebCoreApp process was having a moderate CPU usage (50%) without any web client in use.

    I managed to shutdown the services of IIS and the instances of Dynamics 365 BC and, even when they were stopped, the process still remained at 50% of CPU. I forced to close that process, rebooted the services and now it works fine, but I think it will begin again to give the problem.

    Any other ideas?
