Did you only upgrade the DM cluster? How did you trigger the step of loading full historical data?

However, for the invalid connection error, check the value of the wait_timeout parameter in the downstream TiDB. It’s a Go error, and there’s a high probability that the value is set too low.

TiDB and DM have both been upgraded, and a new task has been created after the upgrade.

It looks like it’s reporting that the user doesn’t have permission, right?

Created a new one with all permissions enabled, but it still doesn’t work.

Resolved, upgrading to version 6.5.1 fixed the issue.
