Here are instructions on how you can download the certificate for any website. For ThingSpeak MQTT broker, you can download the cert from https://thingspeak.com. For the longest lived certificate, you will want to get the certificate of the Certification Authority, in this case Digicert. If you still have trouble, please post what you have tried.
