After migrating the PD node, updating the synchronization task reports a timeout when connecting to the old PD. It seems that some place has cached the old PD information.

Scale-out and scale-in

Did this node disappear from the cluster after scale-out?

After migrating the PD node, you need to restart all modules of the cluster: TiDB, TiKV, and PD.

Is the CDC task running normally?

The CDC task is normal. Except for the inability to update, everything else is functioning properly.

Check if the members have been updated using the command tiup ctl:v6.5.2 pd -i -u http://xxx.

It is the latest PD node information.

After scale-out and scale-in, it is best to perform a tiup cluster reload or restart.
