ping 'shell command' stop working

[Caiota]

Hello guys! I am developing an application a few months (more than a year to be exact) and it has a "ping to server" code and returns its value in MS, however this code simply stopped working infinitely, it only does test 4 times and then stops working. the command is var SAs = app.CreateSysProc ("ping -n -A 52.67.166.50");

Are you sure it was working before?

The only working arguments I have ever seen working for app.CreateSysProc are "sh" or "su"
