The memberlist library fails when it can't find a private address and no
advertise address is given. To return a helpful message to the user,
AlertManager mimics the logic from memberlist. However the code had a
bug that swallowed the error message and made it difficult for the user
to understand how to fix the problem.

memberlist doesn't advertise a valid IP address when the bind address is
empty (":8001") or the unspecified IPv6 address ("[::]:8001).
