ZeroTier with 22.7.4

[fgsfdgfds]

Hi Guys,
Has ZeroTier stopped working since 22.7.4 ?
My OPNsense box is zerotier-ing from behind a starlink.
It was working fine until recently, now my phone can no longer ping OPNsense (when away from yard using zerotier app)
I can ping other machines that are connected to the zerotier network, so it must be OK at zerotier side.
OPNsense shows as being connected, but nothing routes.
Have tried pressing on the package reinstall, but no different.
I did a reboot the other day and that fixed it for a few hours, then nothing again.
Any ideas ?
