what is wrong.

Hello there, @walker

An example of a successful test looks like this:

Since the error complains that it is not a valid live URL, can you please confirm the URL that you are using to access Mattermost on your web / desktop app as well as the DNS resolution result either via nslookup or dig command?

Additionally, may I know if it is a public facing instance? If yes, can you share the URL here?
