Cursor Connection Failed: Network or Outage? | Devdown
Cursor Connection Failed
A connection failure can come from local networking, a proxy, your session, or Cursor itself. Check live components first; when official status is normal, review network, sign-in, and extension version.
Connection failed. Please check your network and try again.Operational
Check live status first, then make one targeted change and wait for the result. Repeated refreshes, sign-ins, or concurrent retries can worsen rate limits and queues. Follow the official incident when a component remains affected; when status is normal and only you are affected, record the error time, network, and account type before contacting support.

Not necessarily. An official component incident is server-side evidence; otherwise check network, proxy, and session first.
Troubleshooting
HTTP 529
The model is up, the queue is full. Official status can stay green. Wait or switch models. Your account is fine.
Claude Code 529
Rate limit
Claude 5-hour and weekly caps, Cursor slow pools — all look operational on status pages. Check Usage in the product, do not wait for this page to turn red.
Cursor Rate Limit
HTTP 429
HTTP 429 means a request was rate limited, not necessarily an outage. Check official status, retry later, and confirm quota and request rate.
/errors/429
Login
When Claude Code, Cursor, Codex, or GitHub Copilot login fails, check official Login status, your session, network, and regional restrictions first.
