The script posted alerts to https://ntfy.silverwal.com/certbot, which is served by the same nginx whose certificates it monitors. A TLS failure on this host would make curl -fsS fail verification and drop the alert describing that failure, leaving only a line in a log nobody reads. ntfy is already bound to 127.0.0.1:2586, so post there instead.
