When attempting to upgrade the firmware on either a ZD1200 or ZD3000 I run into the error "ZD didn't sync the NTP time, please wait or check the network." On each occasion I go into Configure > System time and verify that the time zone is set correctly and sync time with my pc and I still get the same error. Sometimes I reset the ZD after the setting change and I still get the error. It could take several restarts before I am able to upgrade the firmware. Has anyone else run into this issue or am I doing something wrong?
