I’m sending this bug report on behalf of another person.
Their school does computer science assignments through Replit, and a specific assignment requires the usage of network tools, such as ping, nslookup and traceroute. The students are capable of using everything besides ping, which returns the above mentioned errors.
The school deducted that repl blocked ping to prevent possible DDoS attacks from replit (which is completely understandable).
Could you confirm if this is the reason why ping might be intentionally blocked on Replit?
