Sync with server failed [Status Deactivated]

Hi dawin,

Thank you for reaching out to Sophos Community.

Please check licensing.log events on the Sophos Firewall.

==> Login to SSH > 5. Device Management > 3. Advanced Shell

# tail -f /log/licensing.log

Click 'Synchronize' button from GUI and share session output here or in PM.

Ensure that, time & date are set correctly on the firewall.

here is the  error



btw time of the firewall are set correctly

Is the default certificate filled(Certificate > Certificate authorities)?

It would be great if you share few more log lines.
