Problem with configure nginx (I guess) to cooperate with domain and not show ip address.

Hello, I bought a domain from GoDaddy and successfully configured it. When I go to http://mysite.com (just an example), I see my site but domain name (mysite) is translated to ip address. I can’t force nginx (it is nginx, right?) to use and show domain name only and not show ip address. It is a django project.

nginx configuration (/etc/nginx/sites-available/mysite):

server {
    listen 80;
    server_name  mysite.com www.mysite.com XXX.XXX.IP.IP;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/tuliokkj/portfolio-test-project;
    }

    location /media/ {
        root /home/tuliokkj/portfolio-test-project;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/home/tuliokkj/portfolio-test-project/portfolio.$
    }
}

django settings:

###SOME UNIMPORTANT STUFF

SECRET_KEY = '###'

ALLOWED_HOSTS = ['mysite.com', 'www.mysite.com', 'XXX.XXX.IP.IP']

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': '###',
        'USER': '###',
        'PASSWORD': '###',
        'HOST': 'localhost',
        'PORT': '5432',
    }
}

DEBUG = False

if I delete ip address from Allowed hosts and nginx server_name list, I will get something like that:

if I add ip address to server_name in nginx configuration file but still without addin it to local_settings, I will get:

I tried many solutions from nginx tutorials, digitalocean tutorials and nothing helped. I’ll share godaddy configuration also:

I haven’t found language change option so I translated it for you:

I don’t even know if it is problem with django settings (I highly doubt it), ngingx (probably) or godaddy (maybe). Tell me if you need some more information for answer.
