This error keeps popping up every time I run OnTrack on a brand new environment.

In the ServiceCenter the error shows: Exception of type 'System.Web.HttpUnhandledException' was thrown

HttpUnhandledException?

Are you getting it on interval or event or just popping all the time?

When I open the OnTrack app. Here is the stack:

Any update Swatantra Kumar? I'd really appreciate some help. 

Hi Tanveer, Are you using On-Prem version of OutSystems or is it manged instance on cloud?

IIS dispatches the Server.Transfer or the Server.Execute request to the appropriate ISAPI extension based on the extension of the requesting file. For example, a request for an .aspx page is dispatched to the Aspnet_isapi.dll ISAPI extension.


After the request is dispatched to appropriate ISAPI extension, the ISAPI extension cannot call another ISAPI extension. You receive the error message that is listed in the "Symptoms" section because the Aspnet_isapi.dll file, which handles requests to ASP.NET pages, cannot forward the request to the Asp.dll file, which handles requests to ASP pages.


This could also happen that application/component can not intialize the connection.
