Zerotier with Mikrotik

Hi everyone. I have a strange problem with Mikrotik and Zerotier. Firmware updated to version 7.8, both HapAc3 LTE6.

I have an access control system with the main panel under router A and a remote terminal under router B

With Zerotier I created routes to join the two subnets as if they were one. Initially everything worked then now it happens that the connection is blocked. Just power cycle the zerotier interface and everything works for a few hours then crashes again.

The LTE connection is perfect because I reach the Mikrotiks through my vpn and they are always connected.

Zerotier assistance replied that it is not their problem (and in fact I can easily reach both routers through Zerotier)

My Zerotier account is paid

Anyone have experience with this?

I’ve had the same on 7.8 on my RB5009
Not often, but sometimes it was in a state “REQUEST CONFIG” or something. Stopping en starting ZeroTier services made it work again.
Now I’ve update to 7.9(rc2), which bumps the ZeroTier version also to a much newer release 1.10.3
