SOLVED: Nginx http2 issues

[Grass]

So I am using Ubuntu server to run Jellyfin with Nginx, LetsEncrypt and DuckDNS. I got it fully working in Ubuntu server 22.04 and when I upgraded it to 24.04, it broke Nginx (same http2 config file issue) so I reinstalled my OS as well as the other services, yet face the same issue.
When I try to connect to my DuckDNS URL, I get a 502 bad gateway page from Nginx.

When I run sudo nginx -t it says

Code:

2024/09/01 07:34:45 [warn] 1725#1725: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1
2024/09/01 07:34:45 [emerg] 1725#1725: unknown directive "http2" in /etc/nginx/conf.d/jellyfin.conf:12
nginx: configuration file /etc/nginx/nginx.conf test failed

When I disable that line it reads below, but it still is a bad gateway.

Code:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

 

when I don't use the sudo in front of it it reads (but this is not an issue right?)

Code:

2024/09/01 07:36:04 [warn] 1741#1741: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1
2024/09/01 07:36:04 [emerg] 1741#1741: cannot load certificate "/etc/letsencrypt/live/REDACTED.duckdns.org/fullchain.pem": BIO_new_file() failed (SSL: error:8000000D:system library::Permission denied:calling fopen(/etc/letsencrypt/live/ REDACTED.duckdns.org/fullchain.pem, r) error:10080002:BIO routines::system lib)
nginx: configuration file /etc/nginx/nginx.conf test failed

  

I used the documentation for the jellyfin.conf file at https://jellyfin.org/docs/general/networking/nginx

here is my jellyfin.conf file

server {
    server_name REDACTED.duckdns.org;

    # Uncomment to redirect HTTP to HTTPS
    # return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    http2 on;
    server_name REDACTED.duckdns.org;

    ## The default client_max_body_size is 1M, this might not be enough for some posters, etc.
    client_max_body_size 20M;

    # Uncomment next line to Disable TLS 1.0 and 1.1 (Might break older devices)
    # ssl_protocols TLSv1.3 TLSv1.2;

    # use a variable to store the upstream proxy
    # in this example we are using a hostname which is resolved via DNS
    # (if you aren't using DNS remove the resolver line and change the variable to point to an IP address e.g set $jellyfin 127.0.0.1)
    set $jellyfin jellyfin;
    resolver 127.0.0.1 valid=30s;

    ssl_certificate /etc/letsencrypt/live/ REDACTED.duckdns.org/fullchain.pem;

    location = / {
        #return 302 http://$host/web/;
        return 302 https://$host/web/;
    }

    location / {

        proxy_pass http://$jellyfin:8096;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;

        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Protocol $scheme;
        proxy_set_header X-Forwarded-Host $http_host;

        # Disable buffering when the nginx proxy gets very resource heavy upon streaming
        proxy_buffering off;
    }

    location /socket {
        # Proxy Jellyfin Websockets traffic
        proxy_pass http://$jellyfin:8096;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_set_header X-Forwarded-Protocol $scheme;
        proxy_set_header X-Forwarded-Host $http_host;
    }
}

Any help would be greatly appreciated! I have been at this for hours
