Some vmid cannot connect to the gateway

I found that some vmid could not connect to the gateway

With the same configuration, another vmid can be connected normally

Can you look at the differences of the configuration in /etc/pve/qemu-server/ and check it with the output of "ip r s" and "ip a s" both inside the VMs but specifically also on the host?

hello,
Yes, I have checked all the configurations
dhcp ip route All are right

As long as I clone him to another vmid it will work，Even the MAC address is set to the same.
But IPV6 is always available

After I restart the server, they are all back to normal.
