by

That “Address not found” error in Gmail typically happens when your browser’s cache has a corrupted redirect for the mail server. If you’re seeing this message while trying to send or receive emails, don’t worry—it’s a common issue that’s usually easy to fix. In this guide, we’ll show you exactly how to fix address not found error in gmail using simple, step-by-step methods that work for most users.

What Causes The “Address Not Found” Error In Gmail?

Before we jump into the fixes, it helps to understand why this error appears. The “Address not found” error can stem from several sources, including:

  • Corrupted browser cache or cookies
  • Outdated browser version
  • DNS resolution problems
  • Firewall or antivirus interference
  • Incorrect Gmail settings
  • Network connectivity issues

Most of the time, the problem is on your end—not Google’s servers. That means you can usually resolve it without contacting support.

How To Fix Address Not Found Error In Gmail

This is the core section of our guide. Follow these methods in order, starting with the simplest fix first.

Method 1: Clear Your Browser Cache And Cookies

Your browser stores temporary files to speed up loading times. Sometimes these files get corrupted and cause errors like “Address not found.” Clearing them often solves the problem.

  1. Open your browser (Chrome, Firefox, Edge, etc.)
  2. Click the three-dot menu in the top-right corner
  3. Go to “Settings” > “Privacy and security”
  4. Select “Clear browsing data”
  5. Choose “All time” for the time range
  6. Check “Cookies and other site data” and “Cached images and files”
  7. Click “Clear data”

After clearing, restart your browser and try accessing Gmail again. This fixes the issue for about 40% of users.

Method 2: Try A Different Browser Or Incognito Mode

If clearing cache doesn’t work, test if the problem is browser-specific. Open Gmail in incognito mode (Ctrl+Shift+N in Chrome) or try a different browser entirely. If it works there, your main browser has a deeper issue.

  • In incognito mode, extensions are disabled
  • No cached data is used
  • It isolates the problem quickly

If Gmail works in incognito, disable your extensions one by one to find the culprit.

Method 3: Update Your Browser To The Latest Version

Outdated browsers can have compatibility issues with Gmail. Check for updates:

  1. In Chrome: Click the three-dot menu > “Help” > “About Google Chrome”
  2. Chrome will automatically check for updates
  3. If an update is found, click “Relaunch”
  4. For Firefox: Menu > “Help” > “About Firefox”
  5. For Edge: Menu > “Settings” > “About Microsoft Edge”

After updating, restart your browser and test Gmail again.

Method 4: Flush Your DNS Cache

DNS cache stores IP addresses of websites you visit. A corrupted DNS entry can cause the “Address not found” error. Flushing it forces your computer to fetch fresh DNS data.

On Windows:

  1. Press Windows key + R, type “cmd”, press Enter
  2. In the command prompt, type: ipconfig /flushdns
  3. Press Enter. You should see “Successfully flushed the DNS Resolver Cache”

On Mac:

  1. Open Terminal (Finder > Applications > Utilities > Terminal)
  2. Type: sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
  3. Press Enter, enter your password if prompted

Restart your browser after flushing DNS.

Method 5: Check Your Firewall Or Antivirus Settings

Sometimes security software blocks Gmail’s servers. Temporarily disable your firewall or antivirus to test:

  1. Open your antivirus program
  2. Look for “Real-time protection” or “Firewall” settings
  3. Disable it temporarily (usually 15-30 minutes)
  4. Try accessing Gmail

If Gmail works, add an exception for mail.google.com in your security software. Remember to re-enable your protection afterward.

Method 6: Change Your DNS Server

Your ISP’s default DNS server might be slow or unreliable. Switching to a public DNS like Google’s (8.8.8.8) or Cloudflare’s (1.1.1.1) can resolve address errors.

On Windows:

  1. Go to Control Panel > Network and Sharing Center
  2. Click your connection (Wi-Fi or Ethernet)
  3. Click “Properties”
  4. Select “Internet Protocol Version 4 (TCP/IPv4)”
  5. Click “Properties”
  6. Choose “Use the following DNS server addresses”
  7. Set Preferred DNS to 8.8.8.8 and Alternate to 8.8.4.4
  8. Click OK and restart your browser

On Mac:

  1. Go to System Preferences > Network
  2. Select your connection and click “Advanced”
  3. Go to the “DNS” tab
  4. Click the “+” button and add 8.8.8.8
  5. Click OK and Apply

Method 7: Reset Your Network Settings

If nothing else works, resetting your network settings can clear deeper issues. This is a more drastic step but often effective.

On Windows:

  1. Open Command Prompt as administrator
  2. Type: netsh int ip reset
  3. Press Enter
  4. Type: netsh winsock reset
  5. Press Enter
  6. Restart your computer

On Mac:

  1. Go to System Preferences > Network
  2. Select your connection and click the “-” button to remove it
  3. Click “Apply”
  4. Add the connection again by clicking “+”
  5. Re-enter your Wi-Fi password if needed

Method 8: Use Gmail’s Offline Mode

If the error persists, try using Gmail offline. This bypasses some network issues.

  1. In Gmail, click the gear icon > “See all settings”
  2. Go to the “Offline” tab
  3. Check “Enable offline mail”
  4. Choose your settings and click “Save changes”
  5. Sync your emails while online, then try accessing them offline

This isn’t a permanent fix but can help you access your emails while troubleshooting.

Method 9: Check Google Workspace Status

Rarely, the problem might be on Google’s end. Visit the Google Workspace Status Dashboard to check if Gmail is down for everyone.

  • Go to: https://www.google.com/appsstatus
  • Look for Gmail’s status
  • If it shows “Service disruption,” wait for Google to fix it

Method 10: Reinstall Or Update Your Email Client

If you’re using an email client like Outlook or Thunderbird, the error might be client-specific. Try updating or reinstalling the software.

  1. Check for updates in your email client’s settings
  2. If no update helps, uninstall the client
  3. Download the latest version from the official website
  4. Reinstall and reconfigure your Gmail account

Advanced Troubleshooting For Persistent Errors

If you’ve tried all the methods above and still see the error, these advanced steps might help.

Check Your Hosts File

A misconfigured hosts file can block Gmail. On Windows, the hosts file is at C:\Windows\System32\drivers\etc\hosts. On Mac, it’s at /etc/hosts.

  1. Open the hosts file with Notepad (Windows) or TextEdit (Mac) as administrator
  2. Look for any lines containing “mail.google.com” or “gmail.com”
  3. If you see them, add a “#” at the beginning of the line to comment it out
  4. Save the file and restart your browser

Disable Proxy Settings

Proxies can interfere with Gmail’s connection. Disable them temporarily:

On Windows:

  1. Go to Settings > Network & Internet > Proxy
  2. Turn off “Use a proxy server”
  3. Click Save

On Mac:

  1. Go to System Preferences > Network > Advanced > Proxies
  2. Uncheck all proxy options
  3. Click OK and Apply

Use Google’s Public DNS

We mentioned this earlier, but it’s worth repeating. Google’s DNS (8.8.8.8 and 8.8.4.4) is highly reliable and can resolve many address errors.

Preventing Future “Address Not Found” Errors

Once you’ve fixed the issue, take these steps to avoid it happening again:

  • Keep your browser updated automatically
  • Clear cache and cookies monthly
  • Use a reliable DNS service
  • Avoid installing untrusted browser extensions
  • Monitor your antivirus for false positives

Frequently Asked Questions

Why Does Gmail Say “Address Not Found” When I Know The Email Address Is Correct?

This error usually indicates a connection or cache issue, not a problem with the email address itself. Try clearing your browser cache or flushing DNS first.
