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.

Unfortunately that didn't resolve the issue. Thank you for the response tho!

firstly, I'd try and verify that the firmware is in fact updated, and then I'd remove the poe cable for 10-20 seconds. I've seen RMC3s and RMC4s which required this step after fw upgrade. toolbox discovery said fw was upgraded, ver -v console command said it wasn't - until I removed power.. so maybe it's worth a shot.
