Google Firebase은(는) 현재 정상 작동 중입니다

If Firebase isn’t working - for example, your app can’t connect, authentication fails, Firestore doesn’t update, or Cloud Functions return errors - this guide helps you quickly identify common Firebase-related issues and what you can do to resolve them.

Common Firebase Problems and What They Mean

• App can’t connect to Firebase:
  Often caused by network restrictions, incorrect configuration (API keys, project ID), or regional outages.
• Authentication not working:
  Users may be unable to sign in if Auth services are experiencing issues, OAuth providers are unavailable, or redirect domains are misconfigured.
• Firestore / Realtime Database not updating:
  Can be due to quota limits, permission rules, offline persistence issues, or temporary backend delays.
• Cloud Functions failing or timing out:
  Usually related to deployment errors, cold starts, exceeded execution limits, or upstream service failures.
• Hosting site not loading:
  May occur during deployments, DNS propagation, CDN issues, or regional service interruptions.

Quick Troubleshooting Checklist

• Check the Firebase Status Dashboard for service outages
• Verify which Firebase service is affected (Auth, Firestore, Functions, Hosting, etc.)
• Confirm your Firebase project configuration (API key, project ID, app ID)
• Check Google Cloud quotas and usage limits
• Review error logs in Firebase Console and Google Cloud Logging
• Test from another network or device to rule out local firewall or DNS issues
• Disable VPNs or proxies that may block Google endpoints
• Retry the operation after a few minutes if traffic is high

Firebase-Specific Tips

• If Firestore writes fail, check security rules and ensure the client has permission.
• If Authentication redirects fail, verify authorized domains in Firebase Auth settings.
• If Cloud Functions return 500 errors, inspect recent deployments and function logs.
• If Hosting content is outdated, clear CDN cache or redeploy the site.

When to Contact Firebase / Google Cloud Support

If the status page shows no issues but problems persist, consider opening a support ticket or checking Google Cloud service health. Include:

• Firebase project ID
• Affected service (Auth, Firestore, Functions, etc.)
• Region (if applicable)
• Error messages or stack traces

This guide is intended as a first step for diagnosing Firebase issues. For confirmed outages, always rely on the official Firebase Status Dashboard and Google Cloud Service Health updates.
