Node app - WebSocket connection failed, port 8080

When accessing my app the console shows this error.

WebSocket connection to 'wss://' failed:

I also get 404 errors for my login route which I’m assuming are due to the same ws issue.

POST 404

Can anyone suggest a resolution?

Hi there,

The error message shows that you’re trying to establish a WebSocket connection to 'wss://' which seems incorrect. The localhost reference should only be used for local development.

You should be using the domain or IP address of your DigitalOcean App. The URI should look something like 'wss://' or 'wss://' if you’re using a custom domain.

The port should not really be appended as in the DigitalOcean App Platform, your application should be configured to listen on the port defined by the PORT environment variable and the App Platform handles the proxying to the correct service.

I could suggest taking a look at this tutorial here as well:

Let me know how it goes!
