Add SSL support

From a user:

Getting a "jetpack error is that WordPress reports no SSL support. HTTPS NOT working."

Check plugins below and try adding test cert:

Any chance the next release of IWP can come bundled with Really Simple SSL (or similar) and a free (Let's Encrypt) certificate already onboard? Or does that lead to problems when each IWP instance tries to access external sites via HTTPS?

At present, the lack of HTTPS/SSL support (and moreover: lack of documentation on how to set this up) is a real limitation with IWP. The world moved to HTTPS a few years back, and HTTP is barely used anymore. Without obvious HTTPS support, I can't see IWP lasting much longer :-(
