Hey there! We've found the following might help you get unblocked faster:

• 🧵 Deployment URL gives Application failed to respond

• 🧵 Building works but site url returns "Application failed to respond"

• 🧵 deployed my app but not able to access via public url

• 🧵 Public url shows "Application failed to respond"

If you find the answer from one of these, please let us know by solving the thread!

The request does arrive but something is blocking it.

Are you listening on host 0.0.0.0 and do you have the correct port configured in your domain settings under your service settings?

That is the port that is configured in my yml

config

I believe what's happening is the request is reaching your service, your service is trying to give it to the deployment, but no deployment is accepting the request. This is usually relating to either not listening on 0.0.0.0 or not listening on the correct port, are you sure your yml defined port is being respected by your application?

Here you can see that my application is starting on port 8080

This is how I have the public URL configured, I don't understand what's happening.

Did you change the port or something?

I need help, I don't know what else I can do.

1. Ensure your app is actually listening on host 0.0.0.0 and port the port you're mentioning

2. Make sure your app web server is running and allat

Beyond that, I have no clue

Should the app run on :: instead of 0.0.0.0? Can you do a new deployment, do a request and share all the logs? Maybe there is somethin hidden in the logs

Also can you try connecting via ssh to the container and try to do a curl to the app and see if it you get a response?

Also, are you able to connect to the backend from a different app using the internal URL?

Did you try deleting and recreating the public URL?

0.0.0.0 should be used for public networking, and :: should be used for private IPv6 networking. If an app needs both, it will need to bind dualstack. Doing that varies to the framework.

always backend is the heart of application, in backend are you using supabase or neon, neon better, in neon tables are the core or heart, did you see actual content in tables?
