FogBugz importer doesn't work when importing from an instance with a self-signed certificate

Summary

What is the current bug behavior?

Logging will not output any errors and UI will display "Could not connect to FogBugz, check your url".

What is the expected correct behavior?

Improved error message, logging, or support self-signed certificates
