HTTP 301 error when using GsmSSLWebClient example #129

Open per1234 opened 3 years ago

per1234 commented 3 years ago

The GsmSSLWebClient example attempts to access https://arduino.cc/asciilogo.txt, which has been moved to https://www.arduino.cc/asciilogo.txt, resulting in the response:

disconnecting.

I suppose it does still provide a demonstration, but not nearly so user friendly as the previous response:

disconnecting.

I don't know what is the best fix. I found that the MKR GSM 1400 can not connect if I change server to www.arduino.cc:

Starting Arduino web client.
connecting...
connection failed

disconnecting.

server must remain arduino.cc while the Host header value is changed to www.arduino.cc:
