[!warning] STALE / SUPERSEDED — DO NOT USE AS REFERENCE

This document describes the original Contabo deployment (2026-02-05) and is no longer accurate.

• The service was migrated to edge2 CT 102 (10.10.10.20 / Tailscale 100.64.0.33) on 2026-06-16.
• The :3012 websocket port, /notifications/hub Caddy route, dnsmasq split-DNS entry, and /oidc-signin redirect URI described below do not exist in the live deployment.
• Current reference: docs/services/services.md (Vaultwarden entry) and runbooks/lxc-service-migration.md.
• Rollback info: Contabo source is stopped-but-intact; /etc/caddy/Caddyfile.bak-prevault exists on Contabo for instant rollback.

Troubleshooting

SSO Login Loop

Symptom: After SSO auth, redirects back to login screen.

Causes:

1. Access token too short (< 5 min)
2. Missing offline_access scope (no refresh token)
3. Missing signing key (empty JWKS)

Fix:

# Check Authentik provider settings via ak shell
docker exec authentik-server ak shell -c "
from authentik.providers.oauth2.models import OAuth2Provider
p = OAuth2Provider.objects.get(name='Vaultwarden')
print(f'Access Token: {p.access_token_validity}')
print(f'Signing Key: {p.signing_key}')
print(f'Scopes: {list(p.property_mappings.values_list(\"scope_name\", flat=True))}')"

SSO Discovery Error

Symptom: "Failed to discover OpenID provider: Failed to parse server response"

Causes:

1. Empty JWKS endpoint (no signing key)
2. Missing property mappings

Fix: Add signing key and scopes to Authentik provider.
