Tell us what’s happening:
My code in my local ide passes all the test on the American British Translator project but when I push it to GitHub and import it into Replicit, the last two test fails.
You can use localhost for most of the challenges you just can’t submit it as the solution to certificate challenges.
ngrok is not the solution here. You have to host the code somewhere public for the final submission. It needs to stay available and online for as long as possible and not depend on your local machine being online.
