It seems the f/w of the u-blox SARA U-201 seems to puke on if the Amazon Root CA 1 cert is loaded, I've replaced it with the Starfield one. Now connections to www.arduino.cc or aws.amazon.com work for me.
Note: the code now explicitly removes any certs that have 0 size by name. AWS Root is the first.
This resolves #85.
