Server not found in IIS

I've deployed a Mendix App in IIS. My login screen appears no problem, I've added mxclientsystem virtual folder, but as soon as I login, I get a "Server Not Found" message and /xas resource not found. The app is started in a Mendix Console. What could possibly be the problem? Any ideas?

  1. Is your server available locally (localhost:8080)?
  2. If yes: is the ARR or Reverse Proxy correct?
  3. Check whether you can open a static form or image from the site
  4. Rights correct?
