nginx + uwsgi не слушает socket

Подключаю nginx и uwsgi. nginx возвращает 503 ошибку. В errors.log

2021/07/19 18:58:34 [error] 23198#23198: *13 connect() failed (111: Connection refused) while connecting to upstream, client: 104.131.22.119, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.2:8080/", host: "fixmessaging.com"
2021/07/19 19:01:54 [error] 23198#23198: *15 connect() failed (111: Connection refused) while connecting to upstream, client: 104.131.22.119, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.2:8080/", host: "fixmessaging.com"

Почему nginx берет за upstream 127.0.0.2:8080, в sites-enabled/avito_car_bot лежит то что uwsgi_pass слушает avito_car_bot.sock

server {
    server_name avito_car_bot;
    listen 80;

    location / {
        include uwsgi_params;
        uwsgi_pass unix:/home/avito-pokrishki/avito_car_bot/avito_car_bot.sock;
    }
}

В avito_car_bot.ini лежит:

[uwsgi]
module = web.wsgi:app

master = true
processes = 5


socket = avito_car_bot.sock
chmod-socket = 660
vacuum = true

avito_car_bot.sock создается.

Почему nginx берет из 8080, а не avito_car_bot.sock??
