Comment 2 for bug 1919099

There are two different cases here:

- passing a valid address (like 1.2.3.4) which isn't reachable will have a very long timeout (MAAS sends the request but nothing comes back)

- passing an unknown hostname (like "somenonipstring") is (correctly) failing, but hitting https://bugs.launchpad.net/maas/+bug/1922569, which is preventing the error message from being displayed correctly.
