nodes summary information don't show

[laowolf]

I have built a Proxmox VE cluster with two v3.3 nodes.
When I opened the Summary card in the web gui, I found that the CPU Usage, Server load, Memory usage, Network traffic of node A won't show, while all the information of node B displayer normally.
Is this a bug? of have I made some mistake?

OK, it seems right now, although I did nothing....
