Checking the database backup error log in cron shows the above. When I searched, it said that I had to enter the database loose password, so I checked and it was entered.
Even with phpmyadmin, login to the root and user DB accounts works fine.

The backup worked fine until June 23rd, but it doesn't work after that. Where should I check?

When I go to the backup folder, it is actually being backed up, but in the database menu, there is no backup file or backups after June 23rd are not visible.

aaPanel_Kern I already checked and there is nothing wrong. With that password, you can log in as root in phpmyadmin as well.

aaP_master0 After changing the root password, it works fine. Thanks for your support.
