Here is the output: When I connect to port 443 of www.arduino.cc I do not get a connection (which is what I also mentioned in my previous posts -> I have to disable certificate checking on the server to be able to make a connection via ssl) and if I connect to port 80 I get the following output: HTTP/1.1 301 Moved Permanently Content-Type: text/html Date: Mon, 05 Mar 2018 20:11:43 GMT Location: https://www.arduino.cc/asciilog.txt Server: nginx/1.4.2 Content-Length: 184 Connection: Close <html> <head><title>301 Moved Permanently</title></head> <body bgcolor="white"> <center><h1>301 Moved Permanently</h1></center> <hr><center>nginx/1.4.2</center> </body> </html> NO CARRIER Regards, Marc > Sollae Systems wrote: > ------------------------------------ > 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. > Best Regards, > > > > Anonymous wrote: > > ------------------------------------ > > I am using the ezTCP device as a client. > > In the mean time I have changed the setting of our https server for not doing certificate sending and I am now able to create a connection with the server. > > However when I send a HTTP GET request, I only receive the HTTP header, but not the requested data.
