by

Experiencing the ERR_CONNECTION_TIMED_OUT error can be incredibly frustrating, especially when you’re trying to access important websites or run an online business. This common browser error signals that your request to connect with a website took too long, and the server stopped responding. Fortunately, this issue is usually solvable with the right troubleshooting steps.

In this article, we’ll explore what causes the ERR_CONNECTION_TIMED_OUT error, practical solutions for Windows, Mac, and mobile devices, and preventive measures to avoid encountering it again.

What Does ERR_CONNECTION_TIMED_OUT Mean?

The ERR_CONNECTION_TIMED_OUT error occurs when your browser tries to connect to a website but doesn’t receive a response from the server within the expected timeframe. Think of it as dialing a phone number and waiting too long for someone to pick up.

This issue is typically linked to:

  • Network connectivity problems
  • Misconfigured DNS settings
  • Firewall or antivirus blocking the request
  • Outdated browser cache or cookies
  • Website server downtime

Understanding the root cause is key to applying the right fix.

Common Causes of the Error

Before jumping into solutions, let’s quickly go through the most common reasons why this error shows up:

  1. Weak or Unstable Internet Connection – Poor Wi-Fi signals or ISP-related issues.
  2. Overloaded Browser Cache – Old data interfering with the new connection.
  3. Incorrect DNS Configuration – Wrong DNS addresses prevent websites from loading.
  4. Blocked by Firewall or Antivirus – Overprotective security software sometimes misinterprets safe connections as threats.
  5. Server-Side Issues – The website you’re trying to access might be temporarily down.

How to Fix ERR_CONNECTION_TIMED_OUT on Windows

If you’re a Windows user, follow these proven steps:

1. Check Your Internet Connection

  • Restart your router or modem.
  • Switch between Wi-Fi and Ethernet.
  • Test the connection on another device to confirm it’s not a network-wide issue.

2. Clear Browser Cache and Cookies

Cached files can block new connections. On Chrome:

  • Open settings → Privacy and Security → Clear Browsing Data.
  • Select Cached images and files + Cookies → Click Clear data.

3. Flush and Renew DNS

DNS records may be outdated or corrupted. Reset them with these commands:

  • Open Command Prompt (Admin).
  • Enter the following commands one by one:
ipconfig /flushdns
ipconfig /release
ipconfig /renew

This clears old DNS cache and assigns a fresh IP address.

4. Change DNS Servers

Switch to a more reliable DNS service like Google DNS or Cloudflare:

  • Go to Control Panel → Network and Sharing Center → Change adapter settings.
  • Right-click on your network → Properties → Internet Protocol Version 4 (TCP/IPv4).
  • Use the following:
    • Preferred DNS: 8.8.8.8
    • Alternate DNS: 8.8.4.4 (Google)
    • Or 1.1.1.1 and 1.0.0.1 (Cloudflare)

5. Disable Firewall and Antivirus Temporarily

If the site loads after disabling, adjust settings or add the site to the safe list.

6. Reset the Hosts File

A corrupted hosts file can cause connection issues.

  • Navigate to: C:\Windows\System32\drivers\etc\hosts
  • Open with Notepad and remove any suspicious entries.

How to Fix ERR_CONNECTION_TIMED_OUT on Mac

Mac users can resolve the issue using these steps:

1. Check Network Preferences

  • Go to System Settings → Network.
  • Turn Wi-Fi off and on, or switch to another network.

2. Clear Browser Data

In Safari:

  • Click Safari menu → Clear History → Choose “All History.”

3. Flush DNS Cache

  • Open Terminal and type:
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder
  • Enter your password and press Enter.

4. Change DNS Settings

  • Go to System Settings → Network → Advanced → DNS.
  • Add Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1).

5. Check Firewall Settings

  • Navigate to System Settings → Security & Privacy → Firewall.
  • Temporarily disable to test if it’s blocking the site.

Fixing ERR_CONNECTION_TIMED_OUT on Mobile Devices

Mobile browsers can also experience this error. Here’s what to do:

  1. Restart your phone and router.
  2. Clear browser app cache (Chrome or Safari).
  3. Switch to mobile data if Wi-Fi is unstable.
  4. Change DNS in Wi-Fi settings:
    • For Android → Wi-Fi → Modify Network → DNS.
    • For iPhone → Wi-Fi → Configure DNS → Manual.

When the Problem Is Server-Side

Sometimes, the issue isn’t on your end. If the website’s server is overloaded, undergoing maintenance, or misconfigured, you’ll have to wait until the site is back online.

To confirm:

  • Try loading the site from another device or network.
  • Use tools like DownDetector or IsItDownRightNow to check server status.

Advanced Solutions for Persistent Errors

If none of the above fixes work, try these advanced solutions:

  • Update Your Browser – An outdated browser may not establish connections correctly.
  • Reset TCP/IP Settings – Run netsh int ip reset in Command Prompt.
  • Check VPN or Proxy Settings – Disable VPN or proxy temporarily to rule out interference.
  • Reinstall Browser – As a last resort, reinstall Chrome, Firefox, or Safari.

Preventing ERR_CONNECTION_TIMED_OUT in the Future

To minimize the chances of facing this error again, practice these preventive measures:

  • Regularly clear browser cache and cookies.
  • Keep your operating system and browsers updated.
  • Use reliable DNS servers for faster and stable browsing.
  • Maintain strong antivirus software but configure it correctly.
  • Periodically restart your router to refresh connections.

Final Thoughts

The ERR_CONNECTION_TIMED_OUT error may seem daunting at first, but it’s usually caused by simple connectivity or configuration issues. By following the step-by-step solutions outlined in this guide, you’ll be able to restore access quickly—whether on Windows, Mac, or mobile devices.

If the problem persists, it may be a server-side issue that you cannot control. In that case, patience is key until the website’s administrators resolve it.

With proactive measures and the right troubleshooting knowledge, you can ensure smoother, faster, and more reliable browsing.
