Resolution

There are several possible causes for this issue. Attempt each of the troubleshooting steps below in sequence, without skipping any.

  1. Confirm that the vCenter Web Management Service is running.

    To resolve this issue, connect to vCenter locally with a vSphere Client located on the vCenter Server and follow Stopping, starting, or restarting vCenter services (1003895).

  2. Ensure that the correct DNS settings and IP address are being used:
    1. On the vCenter Server, navigate to C:\Program Files\VMware\Infrastructure\VirtualCenter Server\extensions\com.vmware.vim.stats.report\.
    2. Open extension.xml in a text editor.
    3. Edit the line <url>https://FQDN.hostname:8443/statsreport/vicr.do</url> to use an IP address instead of an FQDN to rule out issues with DNS.
    4. Restart vCenter Web Management Service and the vCenter Server Service after making any changes to the .xml file. For more information, see Stopping, starting, or restarting vCenter services (1003895).
  3. Disable any third party web services that may be interfering with the vCenter Web Management Services. 

    To confirm that a third party web service is the cause: 

    1. Stop the vCenter Web Management Service. For more information, see Stopping, starting, or restarting vCenter services (1003895).
    2. Try to connect to port 8443 (the port on which the Web Management Service runs) by executing:

      telnet IP 8443

    3. If the port responds when the vCenter Web Management Service is stopped, there might be another service that is using the port. In this case, if you want to continue running the conflicting third party service, you may have to change the port that Performance Overview uses. To change the port used by Performance Overview, see The Performance Overview tab within vCenter Server reports the HTTP Status 404 error (1016160).
  4. Check if vCenter Server is using custom SSL certificates as a result of a recent upgrade to vCenter Server 4.0 Update 1. For more information, see VMware vCenter Server plugins fail after adding custom SSL certificates (1017577).
Note: Additionally, disable the proxy settings from the browser. 

To disable the settings:

  1. Launch Internet Explorer. 
  2. Navigate to Tools > Internet options.
  3. Click the Connections tab.
  4. Click LAN settings.
  5. Select the Use automatic configuration script option.
