KBA45009: Unable to access Report Manager through N-central

Knowledge Base Article:	45009
Applicable Versions:	N-compass 3.0 and later, Report Manager
Date Created/Updated:	Thursday, July 11, 2019

Introduction

When clicking on Reports > Report Manager in SolarWinds N-central, you may receive a Page Cannot be Displayed error, or other Timeout-related error.

Resolution

There are several points of failure that could cause this symptom. The most common are:

• Report Manager is configured to use an internal IP that is not reachable from the computer you are on.
• You are using Internet Explorer 8+ and it is not displaying the HTTP content within an HTTPS frame. For more information on this issue, refer to Assign browser security zones .

Verify and re-configure Report Manager's network settings

By default, during the install of Report Manager you may be prompted to use the internal IP address of the server on which N-compass is installed. This value is then used to build the Settings that are propagated to SolarWinds N-central.

1. If you leave the IP address as the internal IP, the link SolarWinds N-central uses when you click on Reports > Report Manager will be as follows:
   1. http://<Report Manager >/ReportInterface<Report Manager > will be replaced with the IP or FQDN that you provided on install.
2. This logically will be an issue if you're attempting to access Report Manager from an outside network that cannot access the internal IP of Report Manager. You must re-configure Report Manager to use an externally available IP or FQDN:
   1. Login to the Report Manager Administration Console as the Report Manager Administrator.
   2. Click System Setup and Logs.
   3. Click Advanced Settings.
   4. Review and update the IP addresses or Fully Qualified Domain Name (FQDN) as necessary.
   5. The ExportIP and NCWSURL fields can both be left as an Internal IP address. This value is used by the SolarWinds N-central server to export data directly into the SQL Server databases.
   6. The MenuURL and AdminURL fields should be set to something that can be accessed from the machines that will be used to run reports and administer the Report Manager server. This typically should be an FQDN that will resolve to the devices internal IP within the internal network and to the external IP when accessed from outside.
   7. The ReportServerURL field must be reachable from the local machine where N-Compass is located, as well as from the devices where you intend to run reports and administer Report Manager. This should also be an FQDN that will resolve to the devices internal IP within the internal network and to the external IP when accessed from outside.
   8. Whenever making changes to this page always ensure that you click the Push Settings to All Data Sources button at the bottom to propagate these changes.

Next steps

If the above steps have not worked, then it's likely a browser issue related to Internet Explorer 8+. This is because N-central, by default, uses HTTPS and Report Manager will use HTTP. Internet Explorer will see this as a security risk for Sites not found in the Trusted Sites section of your browser settings. You need to update the following:

1. Add both SolarWinds N-central and Report Manager to your Trusted sites zone.
2. Clear all cache and cookies.
3. Enable Mixed-mode content, which can be done by doing the following:
   1. Go to Tools > Internet Options.
   2. Select Security.
   3. Click Custom.
   4. Scroll down just past halfway, and ensure that mixed content is set to 'enable' and not 'prompt' or 'disabled'.

The browser does need to be restarted before the changes will take effect.
