Please change the URL things.ubidots.com to industrial.api.ubidots.com and try again. After that modification, you should be able to subscribe and publish to your account variables.
The URL things.ubidots.com is only for Ubidots for Educational users. Ubidots STEM and our industrial users should always be using industrial.api.ubidots.com for both publish and subscribe.
