Failed to Start STUN Server Service: 'stun-server.service' Not Found - Troubleshooting Guide

The error message "failed to start stun-server.service: unit stun-server.service not found" typically indicates that the system is unable to locate the stun-server.service file, which is required to start the STUN server service.\n\nTo resolve this issue, you can try the following steps:\n\n1. Verify if the stun-server.service file exists in the correct location. The service file is typically located in the /etc/systemd/system/ directory. You can use the following command to check:\n\n bash\n ls /etc/systemd/system/stun-server.service\n \n\n If the file does not exist, you might need to reinstall the STUN server or manually create the service file.\n\n2. If the service file exists, try to reload the systemd daemon to refresh the service files:\n\n bash\n sudo systemctl daemon-reload\n \n\n3. Once the daemon is reloaded, attempt to start the stun-server.service again:\n\n bash\n sudo systemctl start stun-server.service\n \n\n If the service starts successfully, you can also enable it to start automatically on system boot:\n\n bash\n sudo systemctl enable stun-server.service\n \n\nIf the issue persists, you may need to provide more information about your specific setup and the steps you have taken so far to troubleshoot the problem.
