Overview of NET::ERR_CERT_COMMON_NAME_INVALID

The “NET::ERR_CERT_COMMON_NAME_INVALID” error message pops up when there’s a mismatch between the domain name and the SSL certificate.

Websites use SSL certificates to establish secure connections. If your browser detects that the website’s name doesn’t match what’s on the certificate, it throws this error.

Key reasons for this error include:

• Domain name typo: You might’ve mistyped the URL.
• Expired certificate: Certificates need renewal, usually every 1 to 2 years.
• Wrong certificate setup: Sometimes, the certificate isn’t configured correctly on the server.

You can also experience this issue if the certificate was issued for a different domain name or subdomain. For instance, a certificate meant for www.example.com won’t validate for example.com.

Think about your users. They’ll likely hesitate to proceed if they see this warning. This can harm your site’s credibility right at first glance.

How to Fix It

Fixing this error requires checking a few things:

1. Review your URL: Ensure there are no typos.
2. Check the certificate: Use SSL checker tools to verify certificate details.
3. Renew the certificate: If expired, contact your service provider or renew through your hosting account.

Avoid keeping users in the dark. Communicate clearly if your site undergoes maintenance as you resolve this. Regularly monitor your SSL certificates to prevent lapses.

For users seeking solutions, tools like Auto Page Rank can help monitor these issues efficiently. By ensuring regular audits and alerts, your site can stay secure and credible. Keeping your site’s SEO in check, especially after resolving such errors, helps maintain indexing and visibility.

Common Causes of the Error

Understanding what causes the “NET::ERR_CERT_COMMON_NAME_INVALID” error can clarify how to address it. Recognizing these common issues is crucial.

Incorrect Domain Name

One of the most prevalent culprits is an incorrect domain name. When you type the URL, even a tiny typo can lead to a mismatch.

If your SSL certificate is meant for example.com, but you enter www.example.com, the error surfaces. It’s essential to double-check the URL before passing judgment on your site’s security.

Also, verify that subdomains are included in the SSL certificate. If they aren’t, your users might face this pesky error.

Like many webmasters, you can encounter this. Always pay attention to spelling and structure within URLs to avoid these slip-ups.

Auto Page Rank can help by consistently monitoring your URLs for such typos, safeguarding your site’s credibility.

Expired SSL Certificate

Expired SSL certificates are another common issue. It’s easy to lose track of expiration dates, but ignoring it can be costly.

When an SSL certificate expires, browsers raise a red flag, signaling potential dangers. Users might hesitate to proceed, fearing security risks.

Using tools like SSL checkers can help you track expiration dates. Setting reminders in advance also works wonders.

Frequent checks ensure your certificate remains valid, fostering user trust.

Misconfigured SSL Certificate

Misconfigured SSL certificates create chaos too. Even if the certificate is valid, incorrect installation can trigger warnings.

Whether it’s not including the right intermediate certificates or faulty server settings, these misconfigurations create gaps in security.

You might think everything’s fine, but a simple oversight can lead to trust issues from your users.

Always consult your web host’s instructions for proper installation.

Troubleshooting Steps

Facing “NET::ERR_CERT_COMMON_NAME_INVALID”? Follow these steps to smooth things out.

Check the URL

Start by double-checking the URL.

A tiny typo can lead to major headaches. Look for misspellings or wrong subdomains.

For instance, “https://example.com” and “https://example.co” aren’t the same. That slight difference can trigger the error.

Enter the correct URL in your browser’s address bar and hit Enter. Make sure you’re accessing the right site.

Verify SSL Certificate

Next up, verify your SSL certificate.

Use online tools like SSL Labs or SSL Shopper to get a complete picture of your certificate’s status. These tools quickly highlight any issues with your certificate, like whether it matches your site’s domain.

A valid certificate will show you a green padlock icon in the browser. An invalid one shows a warning. If your certificate’s expired or not configured properly, you might see that irritating error.

Depending on the outcome, renew or replace the cert.

Adjust Browser Settings

Sometimes, it’s not the site—it’s your browser.

Try clearing your browser’s cache and cookies. This can eliminate old data that might be causing conflicts.

Head to your browser settings, usually found in the menu under “Privacy” or “History,” then clear browsing data.

After that, restart the browser and check if the issue persists.

For more critical tweaking, you could even reset your browser to its default settings. Do this with caution—you don’t want to lose essential bookmarks.

Auto Page Rank can help by monitoring your SSL certificates and alerting you before they expire. Stay ahead of potential issues that may disrupt access to your site.
