I don't know much about it either, but you mentioned that the php-fpm configuration may be wrong. It provides a clue that your configuration file uses the unixsock method to connect to php-fpm, check whether the configuration file of php-fpm is set to listen to unixsock? You can take a look at the php-fpm.conf listen, I usually use listening to tcp port 9000

You need to check the log, In the var/log php-fpm or nginx

The default php-fpm.conf is:
listen = 127.0.0.1:9000
Corresponding:
fastcgi_pass 127.0.0.1:9000;
And now you are
fastcgi_pass unix:/var/run/php5-fpm.sock;
So the php-fpm.conf should correspond:
listen = /var/run/php5-fpm.sock

Also, when there is a problem with the configuration service, you should first check the error message in the log.

Does lz seem to use the laravel framework? You can try to create a PHP file in the public folder to check whether the file can be accessed normally.

Delete the last location to replace sock with 127.0.0.1: 9000. 502 is returned when a cgi call fails to be executed.
