Just tried, worked as a charm.
We have no information regarding the ping details. However the service hardly uses ping (ICMP 6) genuine approach.
Setting disabling zone to java discovers the related applet utilizes port 8080 bidirectional activity. Settings enableAll to java allows the “ping” test in full.
We suspect a part of the ping test functionality uses incoming port 8080 activity that can be blocked by a third party, by Windows Firewall or by your internet provider. Sometimes internet providers block well known incoming ports for the security reason.
If the internet connection is maintained by a hardware, the hardware may be a reason as well.
We could suggest a way to verify that by running a temporary web server at port 8080 and asking somebody outside your LAN/provider to try to access the server.
