Failover node enabled in the network? It can be checked in the host list page. Disable the failover node and check again please.

My host now has these ：

Among them, ucloud is a vps pvs with a public network, pvs3541011713 is in a company's intranet environment, pi and maclan are under the same local area network (they can ping each other), and all devices cannot ping, including ucloud.

This is me using maclan to ping a different machine separately

Have you checked the network firewall configuration? For making the host communicating directly each other, ICMP protocol and UDP port 51821-51830 should be enabled.
