Launch Cloud Gateway throws an error message

Hi, Udacity Support Team

I have a problem launching Cloud Gateway through my classroom interface. Every time I click o it throws an error. I will provide a screenshot for you. As I was researching what may have caused occurring that problem, I discovered that many answers were related to exhausted resources on AWS Account. In fact, I haven't used any resources for that time being and I reckon that this is not a problem

Thank you in advance,
