SOLVED: Can't access Jellyfin with my subdomain (NGINX)

[CelianGdfrd]

Hi, I'm trying to install Jellyfin on my Ubuntu server.

ip_address:8096 works, but I can't access Jellyfin with the reverse proxy I've setup.

My Nginx config :

Code:

server {
    server_name REDACTED;

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

    listen [::]:443 ssl; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/REDACTED/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/REDACTED/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}

server {
    # Nginx versions prior to 1.25
#    listen 443 ssl http2;
#    listen [::]:443 ssl http2;

    # Nginx versions 1.25+
    #listen 443 ssl;
    #listen [::]:443 ssl;
    #http2 on;

    server_name REDACTED;

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

    # Comment next line to allow TLSv1.0 and TLSv1.1 if you have very old clients
    ssl_protocols TLSv1.3 TLSv1.2;

#    ssl_certificate /etc/letsencrypt/live/example.org/fullchain.pem;
#    ssl_certificate_key /etc/letsencrypt/live/example.org/privkey.pem;
#    include /etc/letsencrypt/options-ssl-nginx.conf;
#    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
#    ssl_trusted_certificate /etc/letsencrypt/live/example.org/chain.pem;

    # use a variable to store the upstream proxy
    set $jellyfin 127.0.0.1;
    # Security / XSS Mitigation Headers
    add_header X-Content-Type-Options "nosniff";

    # Permissions policy. May cause issues with some clients
    add_header Permissions-Policy "accelerometer=(), ambient-light-sensor=(), battery=(), bluetooth=(), camera=(), clipboard-read=(), display-capture=(), document-domain=(), encrypted-media>

    # Content Security Policy

    add_header Content-Security-Policy "default-src https: data: blob: ; img-src 'self' https://* ; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' https://www.gstatic.c>

    location / {
        # Proxy main Jellyfin traffic
        proxy_pass http://$jellyfin:8096;
        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-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-Proto $scheme;
        proxy_set_header X-Forwarded-Protocol $scheme;
        proxy_set_header X-Forwarded-Host $http_host;
    }
}
server {
    if ($host = REDACTED) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    listen 80;
    listen [::]:80;
#    server_name REDACTED;
    return 404; # managed by Certbot


}

Firefox console tells me that my subdomain leads to a ns_error_redirect_loop, not sure how to deal with this. Nginx Log indicates nothing.

I can provide additionnal information if needed. Thank you very much by advance.
