I'm having issues to Register to the IoT UI Development with ThingWorx class server. I get the following error message.
I've followed the steps as mentioned in M1.2 - Pre-work.
Maybe it works for somebody in the future.
Today I accessed the server, the same way as I did yesterday, and could log in.
It seems that the server gets available after some time (uncertain, 1 day worked for me) after submitting the access code to the course in https://www.thingworxacademic.com
