Hi everyone,

I am currently testing HeathChecks via Docker to see if it meets our needs.
But I systematically run into an error I can't identify the cause.

Every time I try to ping I get a 500 error with the message: ValueError: 'unknown' does not appear to be an IPv4 or IPv6 address

Is this a configuration error?
