Hello,

I'm running a FAST API backend on port 8000 and nextjs on port 3000. Whenever I try to call localhost:8000 or fastapi:8000 (i tried both) I always get

"a server-side exception has occurred (see the server logs for more information)."

Error: connect ECONNREFUSED 127.0.0.1:8000

I am 100% sure the FAST API container/service is running, i can access it from curl requests within the container running nextjs, but not from nextjs specifically. I can also access the service in client components w useEffects, but I'm not sure the best practice on the server-side. I'd really appreciate any help, i've been stuck for a few days now.

Thanks!
