Introduction
Seeing the ERR_CONNECTION_TIMED_OUT error can be frustrating, especially when you need to access an important website. Instead of loading the webpage, your browser displays a message saying the connection has timed out. This error is common in Google Chrome but can also occur in Microsoft Edge, Firefox, and other browsers.
The problem usually happens because your browser cannot establish a connection with the website before the request expires. This may be caused by internet connectivity issues, incorrect DNS settings, browser cache, firewall restrictions, VPN conflicts, or even problems with the website itself.
The good news is that you can usually fix the ERR_CONNECTION_TIMED_OUT error in just a few minutes by following the troubleshooting steps below.
Quick Answer
The ERR_CONNECTION_TIMED_OUT error usually occurs because your browser cannot connect to a website within the allowed time. Restart your router, clear your browser cache, change your DNS server, disable your VPN, and restart your device. If only one website is affected, the problem may be on that website’s server.
Before You Start
Before making any system changes, try these quick checks:
- Refresh the webpage.
- Open another website to see if your internet is working.
- Try the same website on another device.
- Switch between Wi-Fi and mobile hotspot if available.
- Restart your browser.
If the error continues, proceed with the fixes below.
Why Does ERR_CONNECTION_TIMED_OUT Happen?
Several different issues can trigger this error:
- Slow or unstable internet connection
- Router or modem problems
- DNS server issues
- Corrupted browser cache
- Incorrect proxy settings
- VPN connection problems
- Firewall or antivirus blocking the request
- Website server outage
- Network configuration errors
Understanding the cause makes troubleshooting much easier.
Fix 1: Check Your Internet Connection
The first thing to verify is whether your internet connection is working properly.
Open several different websites. If all websites fail to load, the problem is likely with your internet connection rather than your browser.
Restart your router by unplugging it for about 30 seconds before plugging it back in. Wait until all indicator lights become stable and then try opening the website again.
If you’re using Wi-Fi, move closer to the router or temporarily switch to a wired Ethernet connection if available.
Fix 2: Refresh the Webpage
Sometimes the connection simply expires because of temporary network congestion.
Press Ctrl + F5 on Windows or Cmd + Shift + R on Mac to perform a hard refresh. This forces your browser to reload the page instead of using cached files.
If the website loads after refreshing, the timeout was only temporary.
Fix 3: Clear Browser Cache and Cookies
Corrupted browser cache is one of the most common reasons for connection problems.
Open your browser settings and clear:
- Cached images and files
- Cookies
- Browsing data
Restart your browser after clearing the cache and visit the website again.
This also helps resolve many other browser-related errors.
Fix 4: Change Your DNS Server
Sometimes your Internet Service Provider’s DNS server becomes slow or unavailable.
Switch to a public DNS provider such as:
Google DNS
- 8.8.8.8
- 8.8.4.4
Cloudflare DNS
- 1.1.1.1
- 1.0.0.1
Changing DNS often improves browsing speed while solving timeout errors caused by slow DNS resolution.
Fix 5: Restart Your Computer
Restarting your device clears temporary network processes that may be preventing your browser from establishing a connection.
Although simple, this solution often fixes temporary software conflicts.
Fix 6: Disable VPN or Proxy
VPN services sometimes route traffic through overloaded servers, causing requests to time out.
Disconnect your VPN temporarily and try opening the website again.
If you’re using a proxy server, disable it briefly to determine whether it is causing the issue.
Many users discover that the timeout disappears immediately after disconnecting from a problematic VPN server.
Fix 7: Flush the DNS Cache
If your computer is using outdated or corrupted DNS records, your browser may fail to connect to websites even though your internet is working normally. Flushing the DNS cache forces your system to request fresh DNS information.
On Windows
- Press Windows + S and search for Command Prompt.
- Right-click it and select Run as administrator.
- Type the following command:
ipconfig /flushdns
- Press Enter.
You should see a message confirming that the DNS Resolver Cache was successfully flushed.
After completing this step, restart your browser and try accessing the website again.
Fix 8: Temporarily Disable Firewall or Antivirus
Security software protects your computer, but in some cases it may incorrectly block legitimate websites or browser connections.
Temporarily disable your firewall or antivirus and check whether the website loads. If it does, add your browser or the affected website to the software’s allowlist before enabling protection again.
Important: Only disable security software for testing, and remember to turn it back on immediately afterward.
Fix 9: Reset Network Settings
Incorrect network configuration can also trigger the ERR_CONNECTION_TIMED_OUT error.
On Windows
- Open Settings.
- Go to Network & Internet.
- Select Advanced network settings.
- Click Network Reset.
- Restart your computer.
This process reinstalls your network adapters and restores the default network configuration. You’ll need to reconnect to your Wi-Fi network afterward.
Fix 10: Try Another Browser or Device
Sometimes the problem is limited to a specific browser.
Try opening the same website in:
- Microsoft Edge
- Mozilla Firefox
- Safari (Mac)
- Another computer
- Your smartphone
If the website opens elsewhere, the issue is likely related to your browser rather than your internet connection.
Fix 11: Check Whether the Website Is Down
If only one website shows the ERR_CONNECTION_TIMED_OUT error while every other website works correctly, the problem may not be on your side.
The website could be:
- Under maintenance
- Experiencing heavy traffic
- Facing a server outage
- Having DNS problems
In this situation, waiting a while and trying again is often the only solution.
Fix 12: Restart Your Router
If you haven’t already restarted your router, do so now.
Turn it off, unplug it for about 30 seconds, then reconnect the power. Allow the router to fully reconnect before testing the website again.
This simple step refreshes your internet connection and resolves many temporary networking problems.
Common Mistakes to Avoid
While troubleshooting, avoid these common mistakes:
- Restarting your computer without checking your internet connection first.
- Changing multiple network settings at the same time, making it difficult to identify the real cause.
- Permanently disabling your firewall or antivirus.
- Assuming the problem is always your device when the website itself may be offline.
- Ignoring browser updates for long periods.
Working through the fixes one by one is usually the fastest way to identify the cause.
When Should You Contact Your Internet Provider?
If every website displays timeout errors even after trying all the fixes above, your Internet Service Provider may be experiencing technical issues.
Contact your ISP if:
- Multiple devices have the same problem.
- Restarting your router does not help.
- DNS changes make no difference.
- Your internet disconnects frequently.
- Speed tests show extremely slow performance.
Your ISP can check for outages or problems affecting your connection.
Frequently Asked Questions
What does ERR_CONNECTION_TIMED_OUT mean?
