About Claude problems

Claude problems can show up as error messages in the chat, answers that do not finish, or trouble signing in, while claude.ai itself may still load. Usage limits on your plan can stop new messages for a while without any outage. Anthropic's Claude status page lists claude.ai and the API, so check it first when errors appear for everyone.

Official information

Claude official status page (verified )

Our check and Claude's own status page can disagree. We test from one location and read only the homepage response. The provider reports what it knows about its own systems, such as sign-in, apps or single regions. A site can answer our check while one feature is broken, and a regional problem can affect one location but not another.

How this check works

  • One measurement location (single-self-hosted-probe), not a worldwide test.
  • We read only the response headers of the HTTPS homepage; page content and features are not tested.
  • We follow at most 5 HTTPS redirects and check every new address again.
  • The whole check stops after 10 seconds.
  • Results are reused for 60 seconds; this page refreshes its saved check at most every 10 minutes.

Full method and limits

Typical Claude problems

An editorial list of typical problems, not based on live user reports.

  • Usage limit reached Claude shows a limit message when you have used your plan's allowance for the current period, and the message tells you when you can continue. Guide: 429 Too Many Requests
  • Sign-in keeps looping If the claude.ai sign-in page keeps reloading, clear cookies for claude.ai only and sign in again with the same email or account you used before. Guide: ERR_TOO_MANY_REDIRECTS
  • Responses fail with an error An error message instead of a Claude answer that keeps coming back can come from Anthropic's side, so check status.claude.com and retry later. Guide: 500 Internal Server Error
  • Answers stop mid-way Claude streams its answer as it is written, so a network switch can cut a reply short and you need to send the message again. Guide: ERR_NETWORK_CHANGED
  • API key rejected An authentication error from the Claude API means the API key is missing, malformed, revoked or expired, so check it in the Claude Console. Guide: 401 Unauthorized
  • File uploads fail If a file does not upload to Claude, check the file type and size and try again with a smaller or simpler file.

General fixes: AI

  1. Read the exact message AI services can show usage limits and real errors as different messages. A limit message may say when you can continue, while a general error can point to a problem on the service's side.
  2. Start a new conversation Very long conversations or large attachments can fail on their own. Ask the same question in a new chat, with a smaller file if you attached one.
  3. Keep a copy of long prompts Write long prompts in a text editor first. If an answer breaks off or the page reloads, you can paste the prompt again instead of retyping it.
  4. Check the API key and usage For API access, compare the key, the project and the remaining quota in the provider's console before you change your code.
