we used to have the MT unit as a network cloud gateway with ntp server enabled. when we upgrade it from 2.9.51 to 3.19 the ntp server vanished and network devices are not synchronized anymore. even the unit itself cannot work as ntp client with another NTP server.
Thnx normis,
We ve performed the upgrade using the combined package. It seems it does not contain the ntp pack.
Adding it separately solved the problem. Thank you for the support.
