What's wrong? Diagnose fast
529 "Overloaded" error
Anthropic is at capacity. This happens site-wide during peak demand. Retry after 30–60 seconds. API users: implement exponential backoff, not retry loops. Check prismix.dev/service/anthropic to monitor recovery.
Blank page or not loading
Hard refresh first: Ctrl+Shift+R (Win/Linux) or Cmd+Shift+R (Mac). Then try incognito mode with extensions disabled. Stale JS cache and browser extensions cause most claude.ai blank-page issues.
Response stops mid-way / spinner runs
Either daily message limit reached, prompt is too long (context limit), or a connection drop interrupted the stream. Check your usage in claude.ai → Settings → Usage. Try a shorter prompt or new conversation.
Projects not working or losing context
Project file sync can fail silently. Re-upload files in Project settings. If custom instructions are not followed, check that the context window is not exhausted — large files + long chat history fill it fast.
Login loop or "Authentication failed"
Clear cookies for claude.ai and anthropic.com. Sign out completely, then back in. If using Google OAuth, ensure third-party cookies are allowed for accounts.google.com.
Mobile app not working
Force-close the Claude mobile app and reopen. If issues persist, log out from the app, clear app cache (Android: Settings → Apps → Claude → Clear cache), and log back in. Check prismix.dev/service/anthropic for outages.
Step-by-step fix
- 1
Check live Anthropic / Claude status
Go to prismix.dev/service/anthropic. If there is a 529 overload incident, all Claude surfaces are affected and the only fix is to wait. Anthropic also publishes status at
status.anthropic.com. - 2
For 529: wait and retry with backoff
529 means Anthropic's servers are over capacity. Do not hammer the endpoint with retries — this worsens the problem. For claude.ai users: wait 30–60 seconds and try again. For API developers: implement exponential backoff starting at 1s, doubling up to 60s maximum.
- 3
For blank pages: hard refresh then incognito
Press Ctrl+Shift+R (Windows/Linux) or Cmd+Shift+R (Mac). If the blank page persists, open claude.ai in an incognito window with all extensions disabled. Browser extensions — especially ad-blockers, CSP tools, and password managers — frequently break the claude.ai web interface.
- 4
Check your usage and daily limits
Navigate to
claude.ai/settings→ Usage to see your message count and limit. If you hit the free-tier daily limit, wait until midnight UTC for the reset. Upgrading to Claude Pro ($20/mo) gives significantly higher limits and priority access during peak hours. - 5
Fix Project context issues
If a Claude Project is not following custom instructions or losing file context: open the Project → click the pencil icon on your files to verify they uploaded correctly. Large files (especially PDFs) can be truncated. Try starting a new conversation within the same Project to clear accumulated context.
🚨 Understanding Claude's 529 error
HTTP 529 is Anthropic's non-standard status code meaning "we have more demand than capacity right now." It is different from HTTP 429 (too many requests from you personally):
| Error | Meaning | Fix |
|---|---|---|
| 529 Overloaded | Anthropic server capacity | Wait 30-60s, retry with backoff |
| 429 Too Many Requests | Your account rate limit | Upgrade tier or wait for reset |
| 401 Unauthorized | Invalid or expired API key | Regenerate API key at console.anthropic.com |
| 500 Internal Server Error | Anthropic server bug | Check status.anthropic.com, retry later |
Claude plans and message limits
| Plan | Model access | Daily limit | Cost |
|---|---|---|---|
| Free | Claude Sonnet 4.5 | Low (exact number not published) | Free |
| Pro | Sonnet + Opus (limited) | 5× more than Free | $20/month |
| Max | All models incl. Opus | 5× or 20× Pro | $100/$200/month |
| Team | All models | Higher + shared admin controls | $25/user/month |
Daily limits are not published by Anthropic and fluctuate based on server demand. When you hit the limit, you see a message in the chat UI and must wait for the next UTC-midnight reset.

Frequently asked questions
Why is Claude AI not working?
Common causes: 529 overloaded error (Anthropic capacity — wait and retry), daily message limit reached (check claude.ai/settings), blank page from browser extension (try incognito), expired login session (clear cookies and log back in), or API 429 rate limit (upgrade usage tier at console.anthropic.com).
Is Claude down right now?
Check prismix.dev/service/anthropic for live Claude and Anthropic API status, updated every 5 minutes. Also see status.anthropic.com for the official Anthropic status page.
Claude 529 overloaded — how to fix?
The 529 error means Anthropic's servers are at capacity. Wait 30–60 seconds and retry. API developers should use exponential backoff — start at 1s delay, double each retry up to 60s maximum. Do not rapid-fire retries as this worsens the overload. Guide: prismix.dev/guides/claude-overloaded
Claude not responding to messages — what to do?
Check your daily limit at claude.ai/settings → Usage. If the limit is not hit, try a shorter prompt — very long prompts or conversations can exhaust the context window and time out. Start a new conversation to reset context.
Claude Projects not working or losing context — how to fix?
Open the Project settings and verify your files uploaded correctly — sync can fail silently. Large PDFs are often truncated during upload. Starting a new conversation within the same Project resets the context window while keeping the files and custom instructions.
