The VPN connection gets reset and connects multiple times a minute.
NTP server is not setup properly on CMC or Sensor. Commands and results should be as follows:
Command:
# ntpq -p
Good Result:
remote refid st t when poll reach delay offset jitter ============================================================================== +xx.xx.xx.xx xx.xx.xx.xx 5 u 34 64 377 2.869 3.409 2.459 *xx.xx.xx.xx xx.xx.xx.xx 5 u 11 64 377 20.309 1.110 0.380
Incorrect Result:

​Command:
# ps -ef | grep ntp
Good Result:

Incorrect Result:
root 13997 13646 0 15:22 pts/0 00:00:00 grep --color=auto ntp
(usr/sbin/ntpd process is not running)
Situation 1: NTP service is not configured properly: When the ntpq -p command returns 0's instead of values, then the NTP service is not communicating with the NTP server. Please validate that the NTP settings are correct in the Console (Settings > Date / Time). It may help if the CMC and Sensor are on the same VLAN so that they can utilize the same NTP server.
Situation 2: NTP service is not running. Execute one of the following commands to restart the service.
sudo service ntp restart sudo systemctl restart ntp
