Is NALCO Portal Down?

Quick Help for NALCO Portal

If you're experiencing issues with NALCO Portal, try these troubleshooting steps:

Basic Steps

• 1. Check your internet connection. NALCO Portal requires a stable broadband or corporate VPN connection, especially for e-tender submissions and internal dashboards. Run a speed test on another device to rule out local network issues.
• 2. Clear your browser cache and cookies. The portal uses heavy session-based authentication; stale cookies from previous logins often cause white screens or "Access Denied" errors. Clear cache for last 24 hours in Chrome/Edge.
• 3. Test in a different browser or use incognito mode. NALCO Portal works best on the latest versions of Google Chrome or Microsoft Edge. Disable browser extensions like ad-blockers that may block the portal's pop-up forms.
• 4. Restart your router and computer. If you see a "Connection Reset" or partial page load, a simple reboot refreshes DNS and clears temporary TCP/IP glitches that often affect government portal interfaces.
• 5. Verify the system date and time. NALCO Portal uses SSL certificates that fail if your device clock is off by more than a few minutes. Enable "Set time automatically" in your OS settings.

Intermediate Steps

• 1. Check for service-specific maintenance windows. NALCO Portal frequently undergoes scheduled maintenance on Friday evenings (5 PM to 9 PM IST) for e-tender updates and stock reports. If you are locked out or receiving "Portal Under Maintenance", wait 60 minutes and retry.
• 2. Flush DNS and re-authenticate. Open Command Prompt (as Administrator) and run ipconfig /flushdns then ipconfig /registerdns. After this, fully close the browser and log back into the portal using your employee/contractor credentials. This solves most "repeated login loop" errors.
• 3. Disable IPv6 temporarily. NALCO Portal's legacy servers sometimes have IPv6 routing conflicts. Go to Network Settings -> Adapter Options -> Disable IPv6 on your active connection, then reload the portal. This is particularly effective if you get a "This site can't be reached" error despite having internet.
• 4. Check if the issue is limited to specific modules. If you can log in but the e-tender payment gateway or employee leave calendar is stuck on a spinner, try accessing the same feature via the mobile data hotspot (not Wi-Fi) to isolate whether your corporate firewall is blocking certain API endpoints.
