I am using a MKR1400 with an activated Arduino SIM and trying to set up a basic HTTP SSL connection over GSM. I'm using the example web client sketch found here: https://www.arduino.cc/en/Tutorial/MKRGSMExamplesSSLWebClient
I get this output:
OK AT+USECPRF=0,0,1 OK AT+USOCO=0,"arduino.cc",443 ERROR AT+USOCL=0 ERROR connection failed +UUSOCL: 0 disconnecting.
How do I troubleshoot/debug this?
