I would like to ask a question regarding my server problem. I have no idea why it sent 521 code while resources is still fine. I think there is misconfiguration. I am using default of Webuzo panel. Nothing changed. I think the problem leads from php-fpm

FYI, I am using Dual Xeon E5-2670 @2.60 Ghz 32GB server, and here is my php-fpm log

I really appreciate any answers regarding, I have been figured out for almost 8 hours and there is no change. I also use the calculator here: https://spot13.com/pmcalculator/ [which indicates how much to set php-fpm based on our server and script usage] but it is still does not work.
