For this module I see red. Twenty eight failures spanning successive Perl releases

But have you looked at the test results of the fails or just that they are red?

I haven't looked at them all but I checked half a dozen of the fails. Every one I looked at failed in the same place...

    #   Failed test 'success status'
    #   at t/example.t line 19.

    #   Failed test 'have header Client-SSL-Socket-Class'
    #   at t/example.t line 29.

    #   Failed test 'have header Client-SSL-Cipher'
    #   at t/example.t line 44.

    #   Failed test 'found expected document content'
    #   at t/example.t line 46.
    #                   'Can't connect to www.example.com:443 (Name do
+es not resolve)

These are all the places that the tests will fail if the host machine cannot retrieve the webpage www.example.com. To me, this would suggest that the problem is not with the module but instead with an incompatibility between the module's needs and the host environment.

As LWP::Protocol::https is only useful to fetch HTTPS requests, it seems reasonable that the tests fail when the host cannot retrieve a webpage.
