Ping on a specific IP not working

[V0LDY]

Describe the bug

I've just started using Gatus as a replacement fro Uptime Kuma.
Some of the things I monitor are the ping to 1.1.1.1 and 217.61.32.3 (the first node I reach from the WAN interface), to see if internet goes down.
Google's 1.1.1.1 works fine, but I can't get an answer from 216.61.32.3. It worked fine with Kuma and I can ping it from the Gatus container. What could be the issue?

This is my config for those two nodes.

  - name: Primo-Nodo
    group: Internet
    interval: 60s
    url: "icmp://217.61.32.3"
    conditions:
      - "[CONNECTED] == true"
    alerts:
      - type: gotify
        enabled: true
        message: "Primo nodo down!"
        description: "Primo nodo down!"
        priority: 5

  - name: Google-DNS
    group: Internet
    interval: 60s
    url: "icmp://1.1.1.1"
    conditions:
      - "[CONNECTED] == true"
    alerts:
      - type: gotify
        enabled: true
        message: "Google DNS Down!"
        description: "Google DNS Down"
        priority: 5

[TwiN]

I just tried to ping the IP using a handful of online services, and I'm pretty much getting the same result everywhere.

It's not too unusual for icmp packets to be dropped and thus making pings fail. Perhaps another IP would be a better solution?

Do you see an error when hovering over the result in the UI?

Is there an error log?
