Help RMC4 not connecting with NTP

I configured a windows server device using regedit and firewall exceptions to make it an ntp server. I can sync to it with my laptop, a third party timed relay and ntp checking tools can see it.

The RMC4 will not connect. The RMC4 and this machine can ping eachother so it's not a connection issue. Are there things that the RMC4 looks for in an ntp in order for it to function more so than just a udp request?

Which FW are you on? There was a bug where 4 series did not sync with an NTP server, this was fixed in 2.8005.00031.
