Can't make request to routes on EC2-hosted server

I have a node api hosted on an EC2 server. When I ping the base route /, I get back 200 as I would expect, but any further routing beyond that just times out. I've tried it on my local machine, and the routes work fine. I then recreated it in docker and it worked fine. And the fact that the / route works but nothing else (i.e. any /<routename>) can seem to receive the request.
