Fix Settings incorrect or missing a cyper for SSL message #15

Upon first boot, intermittently I get: Settings incorrect or missing a cyper for SSL Connect with mqtt.2030.ltsapis.goog:8883 ClientId: projects/projectid/locations/us-central1/registries/iot-core-tilt-gateway/devices/mhanl-tilt01 Waiting 60 seconds, retry will likely fail

Seems like after an unclean disconnect, IoT core doesn't allow multiple connections from same device ID. Stackdriver log: The connection was closed because there is another active connection with the same device ID

May look into setup/teardown after MQTT send, or something more elaborate.
