Reproducing the Issue

  1. In Crystal Reports, create new report, and in the "Database Expert", select ""
  2. Enter the user credentials and click "OK"
    It fails with the error:
    "Logon failed. 
     Details: Unexpected error; nested exception is:"


  • It fails because there is a Proxy configured on the network to connect to the Internet, but the proxy setting is not added to the connection.


  • Set the proxy configuration for the Crystal Reports connectivity in the file: CRConfig.xml:
    1. Navigate to the CRConfig.xml file, which is by default at the following location:
         - For Crystal Reports 2008: 
                 C:\Program Files (x86)\Business Objects\Common\4.0\java
         - For Crystal Reports 2011: 
                 C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\java\

    2. Open the CRConfig.xml file in a text editor, like: Notepad.

    3. Add the following lines to the <SForce> section of the XML file, with your proxy settings:
         <ProxyAddress> Add the proxy name here </ProxyAddress> 
         <ProxyPort> Add the proxy port number here </ProxyPort>
      Below is an example of how the xml file will look after adding the proxy setting for the connection,
      if the proxy name is: MyProxy, and the port number: 1234

      Note: If you do not know the proxy setting at your company, contact your IT Administrator, or look at the proxy setting in Internet Explorer.
