The ERR_CONNECTION_CLOSED error means that the connection between your browser and the server was unexpectedly closed. This can occur for a variety of reasons, ranging from network issues to problems with the website’s server.
Common Symptoms
When encountering this error, you might see a blank page, or the page may not load at all. The browser will usually display the error message directly or through a page stating “This site can’t be reached” or similar.
Possible Causes of ERR_CONNECTION_CLOSED
Network Issues
Network problems, such as unstable internet connections or network congestion, can cause the connection to drop. This often results in the ERR_CONNECTION_CLOSED error.
Browser Problems
Issues with the browser’s settings, extensions, or cache can interfere with the connection. Sometimes, browser updates or corrupted profiles can also be the culprit.
Website Server Problems
The server hosting the website might be experiencing issues or undergoing maintenance, which can cause connections to be closed unexpectedly.
Firewall or Antivirus Interference
Sometimes, firewall or antivirus software can block or interrupt the connection, leading to this error. Security software may mistakenly identify a secure connection as a threat.
Incorrect DNS Settings
If your DNS settings are incorrect or if there’s an issue with your DNS server, it can lead to connection problems and errors like ERR_CONNECTION_CLOSED.
How to Fix ERR_CONNECTION_CLOSED
1. Check Your Internet Connection
Ensure that your internet connection is stable. Restart your router or modem and check if other devices are experiencing similar issues. If your connection is unstable, you may need to contact your Internet Service Provider (ISP).
2. Clear Browser Cache and Cookies
Cached data and cookies can sometimes cause connectivity issues. To clear your browser cache and cookies:
- Open your browser settings.
- Navigate to the privacy or history section.
- Clear browsing data, including cached images, files, and cookies.
3. Disable Browser Extensions
Extensions can sometimes interfere with your connection. Disable all extensions and check if the issue persists. If the problem is resolved, enable each extension one by one to identify the problematic one.
4. Check Firewall and Antivirus Settings
Ensure that your firewall or antivirus software is not blocking the connection. Temporarily disable the software and see if the problem resolves. If it does, you may need to adjust the software’s settings or add an exception for your browser.
5. Flush DNS Cache
Flushing the DNS cache can resolve issues related to DNS settings:
- Open Command Prompt as an administrator.
- Type
ipconfig /flushdnsand press Enter.
6. Change DNS Servers
Switching to a different DNS server can help resolve DNS-related issues. Consider using Google’s DNS servers:
- Open Network and Sharing Center.
- Go to your network connection’s properties.
- Select Internet Protocol Version 4 (TCP/IPv4) and click Properties.
- Choose “Use the following DNS server addresses” and enter:
- Preferred DNS server:
8.8.8.8 - Alternate DNS server:
8.8.4.4
- Preferred DNS server:
7. Restart Your Browser and Computer
Sometimes, simply restarting your browser or computer can resolve temporary issues. Close all browser windows and restart your computer to see if the problem persists.
8. Check for Browser Updates
Ensure your browser is up-to-date. An outdated browser might have compatibility issues or bugs that could lead to connectivity problems.

If the problem is specific to one website, it may be an issue on the server side. Contact the website administrator or support team to report the problem.
