Does your network do anything that would limit the ability to fetch from outside NTP servers?
If your DHCP server provides an NTP server then Camect will try to use that NTP server (and if an invalid server is being provided, this may cause the problem you're having). If no server is provided by DHCP, it will try
ntp.ubuntu.com and if that doesn't work either it will try
time.google.com.
Debugging the ntp sync requires lower-level logs than what we can get from "Report Bug". If it's not one of the common causes above (i.e. firewall blocking NTP, or DHCP server providing an NTP server that either does not exist or has the wrong time), hook your device to an HDMI monitor and USB keyboard, and send a snapshot of what you see to
sup...@camect.com. We'll send you instructions for what to do after that.
