How to fix or work around API 500 errors
Here are the most effective troubleshooting steps while Anthropic works on the backend:
Check the official status page
Visit status.claude.com first. If it shows “All Systems Operational” but you’re still getting 500 errors, the issue may be regional or intermittent.
Basic refresh and retry
Refresh the page or restart your chat session.
Wait 30–60 seconds between attempts (exponential backoff helps avoid rate limits).
Try incognito/private browsing mode.
