Can no longer ping

Hello,
Having problems with one particular device on windows. This one laptop (windows 11) used to be able to connect just fine but in the last few weeks has developed issues. Possibly related to an update, but unclear on that.
The laptop shows as connected to the ZeroTier network, and it shows up as a connected node on the admin panel.
But it can’t connect to any resource attached to the ZeroTier network. It also can’t be pinged on the ZeroTier managed IP.

Any ideas?
