Server error : An error occured. See dagger.log for information.

> tail mp-log dagger.log

state = self.sdb[sysdns.SYSD_TIME_NTP_STATE_FMT]
SystemError: TIMEOUT
Jul 09 05:07:23 OPCMD: handler "interface"
Jul 09 05:08:03 OPCMD: handler "ha_show.state"
Jul 09 05:08:23 OPCMD: handler "environmentals.all"

Traceback (most recent call last):
File "/usr/share/dagger/ntp_state.py", line 11, in __str__
state = self.sdb[sysdns.SYSD_TIME_NTP_STATE_FMT]
SystemError: TIMEOUT


Environment
  • Palo Alto Firewall.
  • Any PAN-OS.
  • NTP configured.


Cause

The error above will occur when the internal timeout of 8 seconds has run out waiting for a response from the NTP server.

This can occur if:

  • NTP servers not reachable.
  • Reverse DNS lookup on NTP server IP address failed.


Resolution
  1. Make sure that the NTP server can be reached from the firewall.
  2. If a hostname is used, it needs to be resolvable from the firewall.
  3. The DNS server configured on the firewall must have a reverse DNS entry for the IP address of the NTP server
