Not working for you? Try this
- 'Server busy' usually means heavy demandDeepSeek often shows a 'server is busy' message when demand is high. Wait a minute and try again. If it keeps happening to lots of people, you'll see it here in visitor reports and on DeepSeek's status page.
- Try again without search or deep thinkingDeepSeek lists its search service separately from chat. If answers fail with web search or the reasoning mode switched on, try the same question with them off.
- Start a new chatVery long conversations and big file uploads are more likely to fail. Start a fresh chat with only what you need.
- Try a private window or the appOpen chat.deepseek.com in a private window, or try the phone app. If one works, clear site data or update the one that doesn't.
- Check whether your network blocks DeepSeekSome organisations and countries restrict DeepSeek. If it never loads on one network but works on mobile data, it's blocked on that network rather than down.
- API users: read the status codeIn DeepSeek's API, 401 means a wrong API key, 402 means your account balance has run out, 429 means you're sending requests too fast, and 503 means the servers are overloaded. Retry 503s after a short wait.
