I'm filling out all the necessary details for getting the API-key for the free plan (intended for educational and individual purposes) and after pressing "subscribe" nothing happens. It's like it's being processed but then no response after that. Not even an email of confirmation or an error prompt from filling out the form. What am I doing wrong? The only possible reason I can think of is that we're hosting the url locally and not through an official domain, is that a problem?
