This method checks an exception occurred while binding on 0.0.0.0.

If :: is specified in the bind addresses a warning is shown.

The exception is still raised otherwise.

|
|
Binding on both 0.0.0.0 and :: causes an exception on Linux and macOS

because :: binds on both IPv4 and IPv6 (as per RFC 3493).

When binding on 0.0.0.0 after :: this can safely be ignored.
