PSU with reverse proxy


I created a reverse proxy in IIS for PSU. IIS is on the same sever as PSU. It works with a dummy site, but not with PSU. For Apps only an empty page is loaded.
With localhost it works.


I also tried API endpoints. Endpoint works with reverse proxy in browser but not in powershell which would be more much more useful. (It also works with localhost).

Thanks in advance if anyone takes a look.


Enabling anonymous auth on IIS for PSU proxy solved the issue with API endpoints.
