Original GitHub issue: https://github.com/netbirdio/netbird/issues/6927

Describe the problem

Password, PIN, and header service authentication methods are broken on a NetBird Cloud account after setting up a self-hosted proxy/cluster. NetBird-only access works.

All non–NetBird-only auth methods return 400 with invalid session token.

Originally reported in discussion: https://github.com/netbirdio/netbird/discussions/6740

To Reproduce

Free cloud account
Set up self-hosted cluster/proxy (Docker command from management UI)
Add a service with auth method other than NetBird-only access (password, PIN, or header)
Try to log in (browser or curl)
Get 400 / invalid session token

Expected behavior

Password, PIN, and header authentication should succeed the same as before the self-hosted cluster was added.

Are you using NetBird Cloud?

Yes — NetBird Cloud (free) + self-hosted proxy/cluster on Oracle free-tier VPS (public IP, ports 443/80 open).

NetBird version

v0.74.4

Did this work before?

Yes. Service auth worked until the self-hosted proxy/cluster was set up. NetBird-only access was never enabled when it broke. With NetBird-only access enabled, access works fine.

Environment and topology

NetBird Cloud account
Oracle free tier VPS with public IP
Self-hosted cluster using the Docker command provided in the management UI
Reproduced on multiple devices, including Chrome and curl
Tried changing auth method, recreating service, recreating the cluster, changing the domain — issue persists

Impact

Complete inaccessibility of services that require password/PIN/header auth (unless switched to NetBird-only access).

Additional context

Affected area: Login / Authentication / IdP (service auth on reverse proxy)
SSO was not tested
Discussion has had no maintainer response
