exception of schema registry connection timeout

[fmchan]

in the connector workshop https://github.com/confluentinc/commercial-workshops/tree/master/series-getting-started-with-cc/workshop-connectors

I received runtime exception showing the connection timeout of schema registry.
I put https://xxx in the setup property file and tried to telnet 443, it works but if i telnet 80 it doesn't work.
I tested in Mac and Linux, they have the same issue.
