/*
 * ⚠️ ⚠️ ⚠️ ⚠️ Due to the weird issue in Portainer that the healthcheck script is still pointing to this script for unknown reason.
 * IT CANNOT BE DROPPED, even though it looks like it is not used.
 * See more: https://github.com/louislam/uptime-kuma/issues/2774#issuecomment-1429092359
 *
 * ⚠️ Deprecated: Changed to healthcheck.go, it will be deleted in the future.
 * This script should be run after a period of time (180s), because the server may need some time to prepare.
