Follow these steps to check and resolve NTP synchronization issues:

If you encounter this message:

  • Ensure that your firewall or ISP is not blocking traffic to the domain *.pool.ntp.org.
  • Check your upstream devices, such as firewall rules or ISP settings, to confirm that NTP traffic is permitted.
