1. Check whether your index. php has any problems. Maybe you have disabled all error outputs. This is a blank page caused by a problem in php parsing.

2. Your try_files seem to be different from mine. I have been working normally for several years.

try_files $uri $uri/ /index.php?q=$uri&$args;

The same problem has just been solved.
I noticed that your configuration file contains tworoot, SecondlocationThere is$document_root$fastcgi_script_name; Here$document_rootThe value may not be what you expected./var/www/zengzhang.in/To change it to this value. The secondlocationIn$document_root$fastcgi_script_nameChange/var/www/zengzhang.in/$fastcgi_script_name
