Overview

The Sentinel RMS License Manager error code 5, "Cannot talk to the license server on host 'HOSTNAME'. Server not running??", occurs when the client machine is unable to communicate with the license server. This error may also appear as "License checkout failed, license manager error 5", indicating that the software is unable to acquire a license for a requested feature. Several factors, such as network connectivity, server misconfigurations, or missing license details, can cause this issue.

This guide provides step-by-step troubleshooting instructions to resolve the error.

Common Causes of Error Code 5

  1. Incorrect Server Name or IP Address

    • Issue: The client machine may have an incorrect or unreachable server address configured.

    • Solution:

      • Double-check the server hostname or IP address in the application settings.

      • Ensure that the correct license server address is entered on the client machine.

      • If uncertain, verify the server address with the license administrator.

  2. Sentinel RMS License Manager Not Running

    • Issue: The license manager service might not be active on the server.

    • Solution:

      • Check the status of the Sentinel RMS License Manager service on the server.

      • Restart the service if it's not running, which may restore communication.

  3. Network Communication Issues

    • Issue: Network problems can prevent communication between the client and the license server.

    • Solution:

      • Verify Network Connectivity: Run a ping test from the client machine to the server to ensure that the two can communicate.

      • Check for firewall rules on both the client and server to ensure they are not blocking communication.

  4. Anti-Virus or Firewall Blocking Communication

    • Issue: Security software such as firewalls or anti-virus programs might be blocking communication between the client and server.

    • Solution:

      • Review and modify firewall and anti-virus settings on both machines to ensure they are not blocking communication to the Sentinel RMS License Manager.

      • Whitelist the license manager in both the firewall and anti-virus configurations.

  5. Connected Over VPN

    • Issue: VPN connections can interfere with communication between the client and the license server.

    • Solution:

      • Disconnect from the VPN to see if the issue resolves.

      • If the VPN connection is necessary, verify that the correct network routes are in place to allow communication between the client and server.

  6. Incorrect License File Configuration

    • Issue: The license file on the server may have configuration errors, causing license checkout failures.

    • Solution:

      • Examine License File:

        • Locate the license file on the server.

        • Open the file with a text editor and check for errors such as missing entries, incorrect formatting, or invalid license details.

      • Ensure that the license file contains the necessary entries for the software feature you are trying to access.

  7. Outdated License File

    • Issue: An outdated license file might not include the required features or the latest software version.

    • Solution:

      • Contact your license administrator to ensure the license file is current and covers the required features and versions.

  8. Missing Feature in License

    • Issue: The feature or functionality you are trying to access may not be included in your license.

    • Solution:

      • Check the license details to verify whether the feature you are attempting to use is part of your license.

      • If you are uncertain, consult your license administrator.

Additional Troubleshooting Steps

  1. Verify Network Connectivity

    • Ensure that the client machine can reach the license server by running a ping test.

    • Check for firewall rules blocking communication between the client and the server.

  2. Check Server Address

    • Within the application settings on the client machine, verify that the correct license server hostname or IP address is configured.

    • Double-check the server address with your license administrator if needed.

  3. Examine License File

    • Locate the license file on the server.

    • Open the file using a text editor and check for:

      • Missing license entries

      • Incorrect formatting

      • Invalid or expired license details

  4. Review Log Files

    • Access the Sentinel RMS License Manager logs to find specific error messages.

    • Review the logs to identify any errors or warnings that may indicate the root cause of the issue.

  5. Restart the License Manager

    • Sometimes, restarting the Sentinel RMS License Manager service can resolve communication and license checkout issues.

  6. Consult License Administrator

    • If issues persist, consult your organization’s license administrator to verify license details and check server configurations.

Conclusion
