I fixed that like adding another cron.
Type of task: shell script
Execution cycle: Monthly, 1 Day, 0 Hour, 16 Minute
Script content:
find /www/wwwroot/domain.com/wp-content/uploads -type d -exec chmod 755 {} \; && chown -R www:www /www/wwwroot/domain.com/wp-content/uploads
Replace [domain.com] with your web site domain.
