I looked everywhere for this but didn’t find any answer

I have an application, and I decided to run almost every blueprint in its own subdomain .. static ones. example:

1. admin.domain.com > admin interface

2. security.domain.com > anything user related, login log out register ..etc

3. api.domain.com > api

4. domain.com and www.domain.com > normal app

now I know for a fact that my code works perfectly fine, because when I test it using:

1. python run.py

2. flask run

3. uwsgi –socket 0.0.0.0:5000 –protocol=http -w run:app

it worked just fine with the intended result

I am usingubuntu 16.04 if it matters. while testing, I set SERVER_NAME to domain.com:5000. but now since I want to to run in production I changed it to domain.com but it still not working

here are my files:

uwsgi.ini

[uwsgi]
module = run:app
master = true
processes = 5
socket = myrpoject.sock
chmod-socket = 660
vacuum = true
die-on-term = true

/etc/nginx/sites-available/myproject

server {
    listen 80;
    server_name MY_IP domain.com www.domain.com;
    location / {
        include uwsgi_params;
        uwsgi_pass unix:///home/gin/myproject/myproject.sock;
    }
    location ^~ /static/ {
        include /etc/nginx/mime.types;
        root /home/gin/myproject/app/;
    }
}

/etc/systemd/system/myproject.service

and finally my digitalocean droplets without ns:

A           security.domain.com          directs to MY_IP          80
A           admin.domain.com             directs to MY_IP          80
A           api.domain.com                   directs to MY_IP          80
A           www.domain.com                directs to MY_IP          80
A       domain.com                 directs to MY_IP     80

I tried setting www as CNAME but nothing really changed

Right now with these config:

1. www.domain.com and domain.com both works, everything works as intended

2. subdomains don’t work at all, they instead redirect to “welcome to nginx” page
