WampServer

I was able to perform an installation of the ssl certificate in Wamp. But I have a question and if you can help me, I'm grateful:
When installing, in the browser appeared safe navigation
(Green padlock). So far so good. When trying to access my machine with the certificate from another, or from a smartphone through the makeup IP, a response on the smartphone regarding another unsecured browsing machine.
Is it difficult to solve this error? Is the configuration of the certificate, without Wamp or possibly network?
