This is because after submitting the page PHP-FPM Caused by too long processing time . Need to be in php-fpm.conf Set in request_terminate_timeout and php.ini Set in max_execution_time The value of two parameters

Set individual PHP Maximum execution time of script

max_execution_time = 300s

Set up PHP-FPM The timeout for the worker process to process a single request

request_terminate_timeout = 600s

Reload PHP-FPM Then you can save the new item 了
