@alternone - sorry for the inconvenience , have fixed it. We will now validate it only if -ValidateConnection parameter is specified.

Had added this check because we ran into an issue where if you entered incorrect URL, PowerShell itself froze, but looks like that's not happening and is an edge case which we can put behind a parameter.

It will be available from tomorrow's nightly build onwards as well as in the next major release.
