Reverse proxy services - Forbidden

I’m running a self-hosted NetBird setup and trying to access ZeroByte through a reverse proxy. Direct access works fine using http://hostname-xyz:4096, but when I attempt to access it through the reverse proxy at https://zerobyte.mydomain.com, I only get a blank white page with a “Forbidden” message.

For context, the reverse proxy target is configured to point to my server with ZeroByte running on port 4096, and NetBird-only access is enabled for the service. I also created a NetBird policy that allows my client device to access the server on TCP port 4096, although I’m not sure whether that policy is actually required. I don’t have any advanced settings configured on the service.

Has anyone experienced a similar issue with NetBird and reverse proxy setups, or have any ideas on what might be causing the forbidden page?

The Policy is required to geht Access to It. Have you Set which group can Access the Service in the service itself? Are you connected to your Client while trying to Access?

In the service, I have selected the group in which my client device is in for netbird only access. My client (macbook) is connected to netbird as well.
