I tried the HTTP lab, I am good with normal HTTP but can't get https working with the same config as in the workbook.
When I debug http server this is what I get on the server side:
%HTTPS: SSL handshake fail (-6992)
HTTP: ssl handshake failed (-40404)
httpc_request: Have the credentials
http_transaction_free: freed httpc_transaction_t with id 29
http_client_abort_request: Bad Transaction Id
In tried to re-generate the certificats but no luck.
