Routing to asp net core app yields 404

Traefik Traefik v1
1

I am investigating the possibility to use traefik to simulate our azure hosting environment, instead of just using IIS Express to host our site. Most importantly, our sites are hosted under specific ports, and we want to obfuscate this (so as to more approximate an actual scenario).

For example: we have an http site on port 50413 and we want to route this to /test

I have made below configuration, but it does not seem to work, what am I doing wrong?

logLevel = "DEBUG"
defaultEntryPoints = ["http"]


[traefikLog]
  filePath = "traefik.log"

[accessLog]
  filePath = "access.log"


[entryPoints]
  [entryPoints.http]
  address = ":80"

  [entryPoints.api]
  address = ":8888"

[file]

[backends]
  [backends.backend_test]
    [backends.backend_test.servers.server_1]
    url = "http://localhost:50413"

[frontends]
  [frontends.frontend_test]
  backend = "backend_test"
    [frontends.frontend_test.routes.test_1]
    rule = "PathPrefix:/test"
  

[api]
  entrypoint = "api"
  debug = true

It works fine on the dashboard:

But in the logs I see following error:
[access]
