The link couldn't be completed.
A generic catch-all for provider-link failures that don't fit the more specific cases.
What happened
Citadel attempted to bind a third-party identity to your account but the round-trip didn't complete. The most common cause is the consent dance being interrupted (closed tab, revoked consent at the provider screen, slow network).
What to try
- Retry from Settings → Profile → Linked accounts. Most transient failures resolve on a fresh attempt; the original click may have timed out before reaching the provider.
- If you reach the provider's consent screen and decline, the link is intentionally aborted. Re-attempting and approving completes the flow.
- If the failure is consistent across retries, check identity_email_mismatch and identity_already_linked — those two codes carry more specific guidance and are the most common underlying causes.
- If none of the specific cases fit, contact support. Quote E-identity_link_failed and the provider you tried so we can inspect the audit chain.
