## 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:**
```bash
# 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.

### View Logs

```bash
# Vaultwarden
docker logs vaultwarden --tail 100 2>&1 | grep -i -E "sso|error"

# Authentik
docker logs authentik-server --tail 100 2>&1 | grep -i vaultwarden
```
