So this is when I see displayed on the web page:
400 Bad Request
Bad Request
Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.

Additionally, a 403 Forbidden
error was encountered while trying to use an ErrorDocument to handle the request.
