Can this issue be reproduced? It looks like the connection with PD was lost.

It can be reproduced. Every time I use version v5.4.1 for BR backup, it is like this.

Thank you!
In this article, the error in the log during the br backup is the same as mine. I suspect there is an issue or bug in version v5.4.1 of br. For now, I’ll revert to using v5.2.2.
