Weird Nginx Error??? (sh.itjust.works)
submitted 4 days ago by [email protected] to c/selfhosted
11 comments fedilink hide all child comments
 

Good morning/night/evening/the time for you right now, ever since I set up Snikket, my web pages other than Snikket's have been displaying nginx 404 not found errors. I can access the website locally but when I go to the domain name it pops up the error. When I go to localhost:443 it also shows the nginx not found 404 thing so I think that's where my other website pages are getting the error from, but I never port fowarded port 443, at least I don't think so. I use the standard nginx reverse proxy for Snikket, and Nginx Proxy Manager for my other web pages. I really hope someone can help me. Thank you very much in advance.

Post more logs/configs

[–] [email protected] 0 points 4 days ago

What kind of logs should I post?

[–] [email protected] 1 points 4 days ago (1 children)

The ones from the applications which should do the proxying and serving.

BTW: you're using both Nginx Proxy Manager and Nginx in parallel? Native installations, docker, something else?

How are they configured?

[–] [email protected] 1 points 4 days ago (1 children)

nginx proxy manager's in a docker container reverse proxying my nginx docker containers, and native nginx is reverse proxying snikket container because nginx proxy manager doesn't go well with snikket.

Here's the nginx config for my snikket.

server {                                                          # Accept HTTP connections                                       listen 80;

                                                                  location / {                                                        proxy_pass http://localhost:5080/;                              proxy_set_header      Host              $host;
      proxy_set_header      X-Forwarded-For   $proxy_add_x_forwarded_for;
                                                                      # This is the maximum size of uploaded files in Snikket
      client_max_body_size 104857616; # 100MB + 16 bytes          }
}                                                                                                                               server {                                                          # Accept HTTPS connections
  listen [::]:443 ssl;                                            listen 443 ssl;

                                                                  server_name chat.allinuxuser.xyz;                               server_name groups.chat.allinuxuser.xyz;

      proxy_ssl_verify      off;
      proxy_set_header      X-Forwarded-Proto https;
      proxy_ssl_server_name on;

      # This is the maximum size of uploaded files in Snikket
      client_max_body_size 104857616; # 100MB + 16 bytes

      # For BOSH and WebSockets
      proxy_set_header Connection $http_connection;
      proxy_set_header Upgrade $http_upgrade;
      proxy_read_timeout 900s;

  }
}

Here's the docker-compose for one of the sites i'm running that's been affected by the weird nginx error.

version: "3"                                                    services:
    client:                                                           image: nginx
      restart: unless-stopped                                         ports:
            - 5973:80                                                 volumes:
            - ./allinuxuser-website:/usr/share/nginx/html

Please tell me if there's any more logs I need to provide.

So your native nginx process covers ports 80 and 443. which ports does your NPM use? Are you trying to use the same ports? Because that'll most likely clash.

[–] [email protected] 1 points 4 days ago 
services:
  app:
    image: 'jc21/nginx-proxy-manager:latest'                        restart: unless-stopped
    ports:                                                            - '325:80'
      - '81:81'                                                       - '326:443'
    volumes:                                                          - ./data:/data                                                  - ./letsencrypt:/etc/letsencrypt

I mean I got them portmapped to other ports so... I dunno

[–] eager_eagle 1 points 4 days ago (1 children)

find out which process is really binding to 443 if you don't recognize that port as being used

sudo ss -unapt | grep 443

I don't know how to even interpret this, I know it says nginx but which nginx?? I got like 4 nginx web servers running

[–] eager_eagle 1 points 4 days ago (1 children)

you do have an nginx process with PID 2511847 using the port

get more info with

ps aux | grep 2511847

or kill it, if you need to spawn a new one with the right configuration

[–] [email protected] 1 points 4 days ago

apparently it's my native nginx.... wtf. I used

sudo systemctl stop nginx

And the websites that had the nginx error went down. I don't know how this could even happen? My containers use their own nginxes??? Maybe the mix of native nginx and docker nginx is messing everything up, if I can't find a solution I'm probably gonna nuke my native nginx and use docker nginx for all of my nginx needs

[–] [email protected] 1 points 4 days ago

You'll have to look by pid or command line.
