Workflow Development / App Fabric Error - Cannot Read Web.Config RRS feed

  • Question

  • Hi,

    I hope this post is now in the correct forum after being advised that I had initially posted it in the wrong one..

    Anyway, I am having problems with a Windows Workflow Application hosted under IIS/AppFabric.

    Whenever I click on anything to do with any of my persisted workflows in the AppFabric Manager under IIS 7.5, including trying to suspend, delete, terminate a workflow etc, I get the following error message:-

    An Error Occurred when retrieving the list. Review Details for additional information, Filename \\?\D:\Cbs\Cbs.Storm.Services....\web.config. Error. Cannot Read Configuration File

    I have tried everything including assigning custom accounts to the AppFabric Event Collection Service, and Workflow Service as well as assigning a custom account to the AppPool for the application.

    I have also tried setting the security on the folders referenced in the error to allow these custom accounts to read/write files in the respective folder, but all to no avail.

    Any help or guidance would be very much appreciated.

  • Hi Simon,

    According to your description above, it's recommended to enable the failed Request Tracing in IIS, this will give me some hint on why a request has failed, we can enable this Failed Request Tracing in the IIS by steps below,

    1.Open Internet Information Services (IIS) Manager:

    2.In the Connections pane, select the server connection, site, application, or directory for which you want to configure failed request tracing.

    3.In the Actions pane, click Failed Request Tracing...

    4.In the Edit Web Site Failed Request Tracing Settings dialog box, select the Enable check box to enable tracing, leave the default value or type a new directory where you want to store failed request log files in the Directory box, type the number of failed request trace files you want to store in the Maximum number of trace files box, and then click OK.

    You can check log files in C:\inetpub\logs\FailedReqLogFiles, it will give more details to troubleshoot this issue.

    Best regards
