Hello, I am working on deploying my full stack application in a Railway Project. I have successfully connected my backend to the DB and I can test it with the public URL. Now I was trying to connect my frontend to my backend in a similar way to how I connected the DB. Here are the ports of my applications, and the code config I made to set them up + the variable bindings.

Backend

The PORT env variable is also set to 3000.

Basically I think I did everything correctly, according to the docs? This is how I bound the env variable to link the frontend to backend

At this point I am genuinely stuck, and I am unsure where else to check for issues, since the railway-provided logs aren't helping me that much.

When connecting via the public URL, frontend works just fine, so there are no code issues.
