Topic: Google Chrome Connection Errors | Status: Updated
What is this error?
The "ERR_CERT_COMMON_NAME_INVALID" error in Google Chrome indicates a problem with the SSL certificate of the website you are trying to access. Specifically, it suggests that the domain name in the certificate does not match the domain name in the URL you entered.
How to Fix It
- Verify the URL: Check that you've entered the correct URL in the address bar, ensuring there are no typos or extra characters.
- Check for HTTPS: Make sure you are using "https://" at the beginning of the URL instead of "http://." Some websites require a secure connection.
- Clear Browser Cache: Go to Chrome settings, find the "Privacy and security" section, click on "Clear browsing data," and select "Cached images and files." Then, clear the cache and reload the page.
- Update Chrome: Ensure you are using the latest version of Chrome. Navigate to "Settings" > "About Chrome" to check for updates and apply any available updates.
- Access a Different Network: Try connecting through a different Wi-Fi network to rule out any local network issues that may be impacting SSL connections.
- Check Certificate Details: Click on the padlock icon in the address bar to view the certificate details. Make sure the Common Name (CN) or Subject Alternative Name (SAN) matches the domain.
- Contact Website Support: If the issue persists, there may be a problem with the website's SSL configuration. Reach out to their support for further assistance.
