Is Co-WIN Down?

If you're experiencing issues with Co-WIN, try these troubleshooting steps:

Basic Steps

• Refresh & Retry: Press Ctrl + F5 (or Cmd + Shift + R on Mac) to hard-refresh the Co-WIN portal. This clears any temporary page loading glitches.
• Clear Browser Cache & Cookies: Go to your browser settings and clear cached files and cookies specifically for cowin.gov.in. Stale data often causes OTP or booking pages to hang.
• Switch Browser or Try Incognito: Test the site on a different browser (Chrome, Firefox, Edge) or open a private/incognito window. This isolates extension-related conflicts.
• Check Your Internet Connection: Disconnect and reconnect to your Wi-Fi or mobile data. For mobile, toggle Airplane Mode on/off. A weak connection can cause timeouts when loading the vaccination schedule.
• Disable VPN & Ad-Blockers: Co-WIN sometimes blocks traffic from certain VPN IP ranges. Temporarily disable any VPN or ad-blocker extension and reload the page.

Intermediate Steps

• Verify Your Browser Date & Time: An incorrect system clock disrupts Co-WIN's secure session tokens, causing “Invalid Request” errors. Set your device time to Automatic in system settings.
• Clear DNS Cache: Open your command prompt (Windows) or terminal (Mac/Linux) and type ipconfig /flushdns (Windows) or sudo dscacheutil -flushcache (Mac). This forces fresh resolution of Co-WIN’s servers.
• Test on Mobile Data vs. Wi-Fi: If one network fails, switch to the other. Some ISP-level caching on Wi-Fi networks interferes with real-time slot availability on Co-WIN’s main API.
• Update Your OS & Browser: Ensure your operating system and browser are fully updated. Old TLS versions can be rejected by Co-WIN’s security layers, leading to blank pages or “403 Forbidden” errors.

Specific Co-WIN Tip: If the OTP verification step fails repeatedly, wait 2-3 minutes without resending OTP. Rapid resend requests trigger a temporary lock on your mobile number. Also try entering the OTP manually instead of using auto-fill features.
