I've used Unifi equiment with an SH4 for a while now and no real issues. Had a USG for years and yesrs and earlier this year swapped to a UDR.
The UDR has been fine until last week when I had no internet access and the UDR screen was displaying no internet access. I checked the SH4 and it was ok, but the UDR would not work, a few reboots of both devices and nothing so I ended up resetting the UDR and then doing a restore and it conencted to the SH4.
A few days later same issue, this time a couple of power cycles and SH4 and UDR starting talking to each outer.
Again yesterday the UDR lost connection to the SH4, power cycles of both and they connected
I can't seem to work out the issue, Ive change ehternet cables madeno difference so thinking perhaps a software update on one of them has suddenly started this issue.

Are you getting the same WAN IP when it starts working again?
VM might have DAI upstream that gets cleared meaning you need to do DHCP again
Are you able to setup a PC with two NIC with MS ICS so that you can run Wireshark on the WAN with filter
port 68 or port 67 or arp
to see where the problem happens?
Or a switch with two ports VLAN and mirror the WAN to a NIC?
