Grok's generic error, surfacing across the web app, X integration, and mobile apps. It can mean anything from a server-side incident to a stale session token. xAI's own Grok account on X acknowledged this error and recommended specific troubleshooting steps. Unlike the high-demand error, this one can appear even when xAI's infrastructure shows all-green on status.x.ai, pointing to session or account-level issues.
