Has anyone had a speedfusion setup stop windows computers from syncronizing clocks?

Has anyone had a problem with a speedfusion connection to a fusionhub stopping windows 10 computers from being able to syncronize clocks with time.windows.com?
(issue started in late January for me.)


never heard about this problem.
NTP needs UDP Port 123
you can check the Port and test another NTP-Server out of you country.

I would say, it’s a firewall-issue.

I have outbound set to allowed (default rule) and no ports blocked outbound.

I do not have a specific inbound rule for ntp; since it’s stateful firewall it should allow the response to the outbound ntp request without needing a specific inbound port opened, right?
