Failed to access the PD node. Is it because the internal network is not connected, and you can’t access PD?

It’s accessible, everything can be accessed normally. This happens occasionally.

Network issue? Try pinging the PD address from the control machine. Is the latency severe? Are there any packet losses?

Set up a machine for long ping.

Grafana has network monitoring, you can take a look, and also check the PD logs.
