# nginx reverse proxy configuration for nzbstr
# Place this in /etc/nginx/sites-available/nzbstr and symlink to sites-enabled/.
#
# Prerequisites:
#   - nzbstr daemon listening on 127.0.0.1:9117
#   - TLS certificate (e.g. from Let's Encrypt via certbot)
#
# Usage:
#   cp nginx.conf.example /etc/nginx/sites-available/nzbstr
#   ln -s /etc/nginx/sites-available/nzbstr /etc/nginx/sites-enabled/
#   nginx -t && systemctl reload nginx
