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

[CelianGdfrd]

Alright, that's how the top of my .conf file looks now :

Code:

server {
    server_name REDACTED;

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

    listen [::]:80 ssl; # managed by Certbot
    listen 80 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;

    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

And everything works !

Thank you so much for your help !
