Hi MaxT. Welcome to the future!
To fix the “Clock sync failure” issue on your StartOS dashboard, focus on your router’s configuration as follows:
-
Ensure NTP Traffic is Allowed:
- Verify that UDP port 123 (used by NTP) is not blocked by your router’s firewall. Check the firewall settings and create a rule to allow outbound traffic on this port.
-
Check DNS Configuration:
- Confirm that OpenDNS servers (208.67.222.222 and 208.67.220.220) are correctly set in your router’s DNS settings.
- Flush the DNS cache on your router to ensure the new DNS settings are applied.
