Zerotier cannot ping each other

Since I scanned the computer with cleanmymac, zerotier cannot be used. Then I uninstalled cleanmymac and zerotier, reinstalled zerotier, and reinstalled it several times. People in the same network group cannot ping each other. What should I do? Have you encountered such a situation?

I reset the network to its initialized state, cleared the cache, turned off the firewall, and did everything else that needs to be done, but it still doesn’t work.
