Проблема цикличной переадресации на NGINX. Как это исправить?

Question

[darkshy]

Привет, установил по требованию заказчика блоговый скрипт - mastodon.
На данный момент есть несколько проблем:
Проблема в том, что сервер выдает цикличную переадресацию. В чем проблема - понять не могу.
вот конфиг nginx'а:

map $http_upgrade $connection_upgrade {
  default upgrade;
  ''      close;
}

upstream backend {
    server 127.0.0.1:3000 fail_timeout=0;
}

upstream streaming {
    server 127.0.0.1:4000 fail_timeout=0;
}

proxy_cache_path /var/cache/nginx levels=1:2 keys_zone=CACHE:10m inactive=7d max_size=1g;

server {
  listen 80;
  listen [::]:80;
  server_name blogs.slainscraft.com;
  root /home/mastodon/live/public;
  location /.well-known/acme-challenge/ { allow all; }
  location / { return 301 https://$host$request_uri; }
}

Остальные проблемы были решены в момент написания этого вопроса.

А у Вас в коде блога случаем нет перенаправления на http?

[dodo512]

Похоже запросы принимает cloudflare и проксирует на ваш сервер уже по http, а там у вас редирект на https.

[darkshy]

Решил тестировать дальше, в итоге отключил полностью cloudflare с данного поддомена, появился новый прикол:

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)

nginx: [emerg] bind() to [::]:443 failed (98: Address already in use)
nginx: [emerg] still could not bind()

а сам домен начал выдавать, что мол нет такого сайта.

[darkshy]

Sand, нет, по крайней мере у разработчиков мастодонта все в порядке

[Lynn «Кофеман»]

darkshy, Address already in use — значит у вас уже запущен nginx (или другой веб-сервер) на этом порту.
