Getting 500 internel server error while deploying django application inside digital ocean

Question

I have been trying to deploy django application inside digital ocean ubunut vps for 12 hours. But can't solve this issue. Everything running just fine gunicorn, nginx eveyrhting looks good but still getting this error. Even tried to run it using my ip address:8000 and it ran well also.

Here is the status of gunicorn:

This is the status for gunicorn.socket:

Here is the nginx -t:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

here is my gunicorn service:

[Unit]
Description=gunicorn daemon
Requires=gunicorn.socket
After=network.target

          --bind unix:/run/gunicorn.sock \
          LeadScrapper.wsgi:application

[Install]
WantedBy=multi-user.target

Here is my nginx:

server{
        listen 80;
        server_name 134.209.71.166;

        location = /favicon.ico { access_log off; log_not_found off; }

        error_log /root/logs/nginx_error.log;


        location /static/ {
                root /leadscrapper.nl;
        }

    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
    }
}

I have no idea why I am getting this error!! Can someone come forward to help me solve this issue?
