Advice Generator w/ vanilla JS

Hey guys, haven't submitted a challgenge for a while, I've been focused on learning more about javascript and chose this challenge to practise some of my recent knowledge. Quick question, I'm hosting my code on gitHub and using gitHub pages, seems that my live page on gitHub pages isn't making the API call but it works on my local environment. Did some research on this and apparently it's gitHub that blocks API calls, if someone can explain to me if that's what happening would be awesome. Any advices or tips are welcome. Happy code to all
