Claude AI은(는) 현재 정상 작동 중입니다

If Claude.ai isn’t working as expected - such as replies failing, slow responses, login issues, or features being unavailable - this guide focuses on the most common Claude-specific problems and how to resolve them.

Common Claude Issues and How to Fix Them

• Claude says “Something went wrong” or fails to respond:
  This often happens during high server load or temporary backend issues. Refresh the page, wait a minute, and resend your prompt. Shortening the prompt can also help.
• Responses are extremely slow or time out:
  Claude may be under heavy usage. Try again after a few minutes, reduce prompt length, or start a new chat session.
• Claude stops mid-response:
  This can occur due to connection issues or internal rate limits. Refresh the page and ask Claude to continue, or rephrase the prompt.
• Can’t log in or stuck in a login loop:
  Usually caused by browser cookies, cached sessions, or blocked authentication scripts. Clear cookies for claude.ai or try another browser.
• Uploads or attachments fail:
  File uploads may fail if the file is too large, unsupported, or if the session is unstable. Try a smaller file or reload the page before uploading again.
• Features missing (models, tools, or UI options):
  Claude rolls out features gradually. Missing options may be account-specific or temporarily disabled during updates.

Quick Troubleshooting Checklist

• Refresh the page or start a new chat
• Log out and back in to reset your session
• Clear browser cache and cookies for claude.ai
• Disable browser extensions (especially ad blockers or privacy tools)
• Turn off VPNs or corporate firewalls that may block requests
• Try a different browser or device
• Reduce prompt length or complexity
• Wait a few minutes if Claude appears overloaded

What Often Causes Claude Issues

• High traffic or peak usage times
• Backend model updates or feature rollouts
• Long or complex prompts hitting internal limits
• Browser session or authentication problems
• Network restrictions blocking API requests

When to Contact Claude Support

If problems persist and none of the steps above help, contact Claude support. Include:

• The exact error message (if shown)
• What you were trying to do (prompt type, file upload, model used)
• Browser and device information
• Approximate time the issue started

This page is intended as a first-step troubleshooting guide for Claude.ai. If the issue is widespread or persistent, it’s likely a service-side problem and will resolve once systems stabilize.

FAQ – Common Claude.ai Issues & Fixes

• Is Claude down right now?

  If Claude.ai is not responding or won’t load, it may be due to a temporary outage or high traffic. If multiple users are experiencing the same issue, the service may be down. If only you are affected, the problem is usually related to your browser, internet connection, or local settings.

• Why is Claude not responding or stuck on loading?

  If Claude is stuck on loading or not responding, it is often caused by high demand, a network issue, or a browser problem. Refresh the page, try a different browser, disable extensions, or check your internet connection to restore functionality.

• Why am I getting a rate limit or usage limit on Claude?

  Rate limits on Claude occur when you exceed the allowed number of messages within a time period. This is normal on free or subscription plans. Waiting a few minutes or upgrading your plan usually resolves the issue.

• Why can’t I log in to Claude.ai?

  If you can’t log in, check that you are using the correct email method (Google, email link, or SSO). Clear your browser cache, disable VPNs, and try again. Login issues are often caused by authentication errors or temporary service interruptions.

• Why can’t I upload files or images to Claude?

  If file uploads are not working, it may be due to file size limits, unsupported formats, or temporary feature restrictions. Refresh the page, try a smaller file, or switch browsers. Some features may also depend on your plan or availability.

• Why does Claude give incorrect or inconsistent answers?

  Claude, like all AI systems, can sometimes produce inaccurate or inconsistent responses. This can happen due to missing context, ambiguous prompts, or model limitations. Improving prompt clarity usually helps generate better results.

• Why is Claude running slowly?

  Slow performance is usually caused by high server demand, long conversations, or complex prompts. Try starting a new chat, simplifying your input, or refreshing the page to improve speed.

• What should I do if Claude.ai is not working?

  If Claude.ai is not working, try refreshing the page, switching browsers, disabling extensions, and checking your internet connection. If the issue continues, it may be a temporary outage on the platform side.
