NGINX - Why i am getting "Permission denied" error code 13? - nginx

Question

i finished setup of my first nginx server and i noticed the following error on nginx t command.
Error mesage:
nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied)
2020/12/12 19:25:26 [warn] 1498#1498: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
2020/12/12 19:25:26 [emerg] 1498#1498: open() "/run/nginx.pid" failed (13: Permission denied)
nginx: configuration file /etc/nginx/nginx.conf test failed
My NGINX config file as is now:
user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;
events {
worker_connections 768;
# multi_accept on;
}

auth_basic "Restricted Content";

# Harden nginx against DDOS
client_header_timeout 10;
client_body_timeout 10;
keepalive_timeout 10 10;
send_timeout 10;
}
How can i fix this error? Is my config file fine? I am using a raspberry pi as a home server for my projects. I am using SSH to communicate with my server and i am able to read with sudo nano the error log file.

MUST use sudo and not simple nginx t...
The correct command:
sudo nginx -t
And the output:
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
