Wordpress + Nginx - openat() ... failed (13: Permission denied)

Hello,

in the web log, whenever you call the wordpress plugin I get this error

Code:

2021/05/13 21:55:44 [crit] 2918#2918: *15 openat() "/var/www/finance.smidl.online/finance/" failed (13: Permission denied), client: 52.212.240.116, server: finance.smidl.online, request: "POST /?rest_route=%2Ffapi%2Fv1%2Fcallback&level%5B0%5D=55&days=14 HTTP/1.1", host: "finance.smidl.online", referrer: "api.fapi.cz"

nginx.conf

Code:

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
        worker_connections 1024;
        # multi_accept on;
}

http {

map $remote_addr $ip_anonym1 {
default 0.0.0;
"~(?P<ip>(\d+)\.(\d+)\.(\d+))\.\d+" $ip;
"~(?P<ip>[^:]+:[^:]+):" $ip;
}

map $remote_addr $ip_anonym2 {

"~(?P<ip>(\d+)\.(\d+)\.(\d+))\.\d+" .0;
"~(?P<ip>[^:]+:[^:]+):" ::;
}

map $ip_anonym1$ip_anonym2 $ip_anonymized {

}

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;
}

Where could the problem be?

 

I think nginx.conf is the least to do with the problems and you should look into your wp domain logs and vhost but I would normally check if I got the necessary wp nginx directive in the vhost before checking the logs for error.

 

Could I ask for more specific guidance? The site log reports that the third-party service does not have API permissions to the site folder.

Code:

2021/05/13 21:55:44 [crit] 2918#2918: *15 openat() "/var/www/finance.smidl.online/finance/" failed (13: Permission denied), client: 52.212.240.116, server: finance.smidl.online, request: "POST /?rest_route=%2Ffapi%2Fv1%2Fcallback&level%5B0%5D=55&days=14 HTTP/1.1", host: "finance.smidl.online", referrer: "api.fapi.cz"

Is it possible that this is by setting permissions on folders and files? Folders have 755 and 644 files.
