You're reaching CloudFlare because Isracard uses the CloudFlare CDN in
order to cache and secure the website. I assume they're specifically using
CloudFlare's Web Application Firewall service to block unwanted requests at
the perimeter instead of allowing unwanted traffic to make it to their
servers.

As such, digital.isracard.co.il is resolving (using CNAME records) to
CloudFlare's service.

Keep in mind that "ping" and "traceroute" aren't proper tests for
connectivity to HTTP and HTTPS services. Most platforms, including
CloudFlare, will block these requests (both are based on ICMP packets, not
TCP). A better check would be something like tcptraceroute, but even those
may be blocked by Web Application Firewalls (WAF) for a multitude of
reasons, including identifying the request as a "scan" due to its low TCP
TTL values.

Anyways, the reason you're not getting through seems to be that CloudFlare
thinks you're a risk for some reason.
