Solution
Errors
500 and
503 can be caused by improper installation, firewall and security settings, incorrect network settings, insufficient memory, or insufficient server specifications. Follow the steps below to fix these errors:
- If this error appears when attempting to access the server's URL from a client system, check whether the SystemsManagement service is running on the server.
- This can be checked from the NI SystemLink Service Manager tab of the NI SystemLink Server Configuration application.
- If this service has stopped running, verify that the client has the correct DNS configuration (i.e. that the computer name matches the IP address). If there is a DNS problem, it will be necessary to:
- Delete the client system from SystemLink.
- Flush the DNS.
- Stop and restart the net logon.
- Reconnect the client in SystemLink.
- If several SystemLink modules have been installed, remove any that are not actively used.
- If you're unsure about which modules are installed, search NI Package Manager for:
- To uninstall these modules, refer to Uninstall NI Software or Drivers Using Package Manager.
- Note: From SystemLink 2020 R1, the SystemLink Software Configuration Module is required to manage and view client connections.
- Ensure that your server PC meets the minimum specification requirements.
- View the requirements in the Readme document. The Readme for each SystemLink version is found on the download page.
- Note: If using the SystemLink TDM DataFinder module, NI strongly recommends having more RAM, Disk space and CPU cores than the specified minimum. This is because the TDM DataFinder Module requires the use of databases, which will grow in size depending on your use case.
- Verify that all SystemLink services are running.
- In the Windows Services application, all services starting with "NI SystemLink" should be set to Running and Automatic.
- In the SystemLink Server Configuration application, all services should be running under the NI SystemLink Service Manager tab. If any are not running, try restarting them and following any troubleshooting prompts in the Troubleshooting tab.
- If using a firewall, follow Network Ports Required for SystemLink to ensure that all necessary firewall ports are open.
- If using any Group Policies or anti-virus software, work with your IT department to disable these features and try again.
