Unexpected Error

[valdr]

When attempting to run the tool, I get the following error:

An unexpected error has occurred.
Were sorry, but the detection server has failed due to an unexpected error.

Unexpected server error
code: ENOTFOUND
syscall: queryAaaa
hostname: <IP Address redacted>

Stack:
Error: queryAaaa ENOTFOUND <IP Address redacted>
    at QueryReqWrap.onresolve [as oncomplete] (internal/dns/promises.js:172:17)

There is no domain name, the server runs with an IP address only (Test-server, port 80 purposely opened to the world, will be closed again)
