UpDraftPlus Clone failure | WordPress.org

I’ve tried several times to create a clone of my live site. The process never completes. I’m getting failure messages in the log but none help me understand how to fix the problem or suggest anything I’m doing incorrectly.

Any suggestions on how to move forward would be appreciated.

The last few lines in the log file are as follows:
