Question
Deployed in style (kilt included), but app still not reachable

My Node.js app runs fine on my droplet (Ubuntu 22.04). curl localhost:3000 gives the expected output, but I can’t access it from outside via the public IP.
-
UFW is open on port 3000
-
App’s listening on
0.0.0.0:3000 -
No reverse proxy or SSL yet — just raw testing
I thought wearing a kilt might grant me dev magic. Turns out, I might just need proper networking advice.
Thanks in advance!

Hi there,
If
curl localhost:3000works but hitting it from outside doesn’t, and UFW is open on port 3000, there are a couple things to double-check:First, make sure your app is actually listening on
0.0.0.0and not justlocalhost. Sounds like you’ve done that, but it’s worth verifying with:Next, check if your cloud firewall (from the DigitalOcean control panel) is blocking port 3000. Even if UFW is open, the cloud firewall takes priority, you’ll need to explicitly allow TCP traffic on port 3000 there.
Once that’s done, try again via your public IP and port 3000. If it still doesn’t work, try temporarily disabling UFW just to rule it out:
If it works with UFW off, then something’s off in the UFW config.
Once you’ve got it working, you can throw Nginx in front later, but for now, that should get you going.
Let me know how it goes!
