Dear Marc, Thank you for your information. For further analysis, could you please connect to a widely-known HTTPS server, send a GET request, and show us the screenshots of response message, in case you active and deactive SSL option. For example, you may connect to HTTPS server 54.235.185.199 (https://www.arduino.cc/), and send a HTTP GET request such as "GET /asciilogo.txt HTTP/1.1". Thank you very much for your understanding.
