App Platform – disable load balancer rerouting on port 80

If I deploy an app on DO’s platform with HTTP Port set to e.g. 1337, with the URL, I cannot access

My understanding per is that a load balancer will reroute port 80 requests.

Why is this? Can one kill all port 80 / 443 redirects and only expose the HTTP Port?

Hi @randomuser,

The port you defined in the App Platform as HTTP_PORT is the port on which your service is listening on. But initially, the load balancer gets requests on port 80/443. The architecture works in this way, so you cannot directly access the app by appending :<http_port> at the end of your APP_URL. You need to use the APP_URL given to access your app and it will automatically handle the port forwarding/redirections.
