           Why are certain ports restricted for HTTP health probes?
         answer: |
           The following ports are restricted for HTTP health probes: 19, 21, 25, 70, 110, 119, 143, 220, 993. These ports are blocked for security reasons by WinHTTP, meaning that Load Balancer health probes are unable to use these ports. For more information, see [What's New in WinHTTP 5.1](/windows/win32/winhttp/what-s-new-in-winhttp-5-1#changes-to-default-settings).

+          ICMP ping is currently not supported by Azure Load Balancer. You can use any tool that supports TCP ping instead to test your load balancer's connectivity.
