    #auth_basic_user_file /etc/htpasswd;

    #rewrite ^/autobrr/(.*) /$1 break; # required for versions < v1.55.0, or when baseUrlModeLegacy = true in v1.55.0+
}

Heads up

Don't forget to set the baseUrl option in the config.toml:

# Base url
# Set custom baseUrl eg /autobrr/ to serve in subdirectory.
# Not needed for subdomain, or by accessing with the :port directly.
#
# Optional
#
baseUrl = "/autobrr/"

Subdomain

server {
    listen 80;
    server_name autobrr.domain.com;
    return 301 https://$server_name$request_uri;
}

    listen 443 ssl http2;
    server_name autobrr.domain.com;
