Describe the problem

When the SSO session (Azure AD OpenID Connect) expires, the NetBird client remains in a "Connected" state (Management: Connected, Signal: Connected) but peer connectivity silently degrades. Some peers show as "Connecting" indefinitely and traffic no longer flows to them, while the client never triggers a re-authentication prompt.

The only workaround is to manually run netbird down followed by netbird up, which triggers a new SSO login flow and restores full connectivity.

This makes the client unreliable for long-running machines (servers, CI runners, etc.) where no user is around to notice the silent failure and manually cycle the connection.

To Reproduce

Set up a self-hosted NetBird deployment with Azure AD OpenID Connect as the identity provider.
Connect a client via netbird up and complete the SSO login.
Wait for the SSO/OAuth token to expire (depends on Azure AD token lifetime policy).
Observe that netbird status still shows Management: Connected and Signal: Connected, but traffic through netbird doesn't work
Run netbird down && netbird up — SSO re-authentication is triggered and all peers reconnect normally.

Expected behavior

When the SSO token expires, the client should either:

Automatically refresh the token using a refresh token (if available), or
Detect the expired/invalid session and trigger a re-authentication flow automatically, or
Surface a clear status change (e.g., "Needs Login" / "Session Expired") rather than silently remaining in a "Connected" state with broken peer connectivity.

Are you using NetBird Cloud?

No — self-hosted NetBird control plane (management, signal, relay, dashboard), with Azure AD (Entra ID) configured.
Running on version 0.66.2

NetBird version

0.66.2 (happens with all recent tested version)

@gbhelp commented on GitHub (Mar 9, 2026):

Probably happens with other SSO providers too. I'm using Keycloak and having the same problem.
I'm going to have a look at the token expiration.

+1

Using selfhosted Netbird with PocketID and same issue on several clients.
