"If there was a routing problem you wouldn’t have been pinging anything."

Actually you could still ping if the router was set-up to pass only the port that ping is using, and stop all others.

“Actually you could still ping if the router was set-up to pass only the port that ping is using, and stop all others.”

‘ping’ is ICMP protocol 8, it doesn’t use a port.

What you’re describing is an access control list.

Very unlikely.
