Ping test continously failing in my machine

Hi,
When I am running the test, the ping test is continuously timing out in my machine. When I try to ping the same domain via terminal, the ping works file.

Does anyone know the difference between implementation of pythonping vs OS ping?
I am able to ping my local gateway using both os ping and pythonping. Anything from another network is throwing timeout in pythonping while works file in os ping. The failure happens even when I give directly the ip address instead of hostname (found via traceroute).
