What Is an SSL Certificate Error?

An SSL certificate error is a browser’s inability to establish a secure connection with the website’s server. When the browser can’t verify the SSL certificate’s identity for one reason or another, instead of connecting users to the website, it warns them that the site may be insecure.

SSL certificate errors pose security, financial and reputational risks to websites if not fixed promptly.

Why Am I Getting SSL Errors?

You’re getting SSL errors because something is wrong with the website’s SSL certificate configuration. When your browser attempts to connect with the server, it performs a series of checks known as SSL handshake to establish encryption algorithms and key exchange. If an element is missing from the server or browser side, the connection will be aborted, and the SSL error will occur.

Most Common SSL Errors

The thing with SSL certificate errors is that they could be caused by anything from a wrong date on your PC to an expired intermediate certificate on the server side. Sometimes, you will try different fixes before finding the culprit and eliminating the issue.

Below we’ve compiled an extensive list of most common SSL errors to help you troubleshoot and fix SSL connection issues.

  3. Mixt HTTP and HTTPS Content Error
  4. SSL Certificate Name Mismatch Error

How to Fix SSL Errors as a Website Owner?

If browsers suddenly don’t trust your website and display an SSL connection error, it’s time to take immediate action. You don’t want visitors to see the off-putting security warning and have a negative impression of your site or brand.

As a website owner, it’s your responsibility to ensure secure connections and protect users’ sensitive data against cyber attacks. So, when an SSL certificate error pops up, you must fix it quickly. Here’s how you should tackle the SSL issues:

1. Determine whether your server or the browser is causing the problem. The quickest way to pinpoint any SSL error is to scan your SSL certificate with an SSL testing tool. You will get instant reports on critical parameters like protocol support, handshake simulation, cipher suites, and more. If something is wrong with your SSL certificate or server, the testing tool should catch it and suggest a solution.

2. Check your hosting platform and certificate authority. Most times, server-side SSL errors come from improper SSL installation configuration and management. If you host your website on a reliable platform, the chances of a security issue are slim. Commercial hosting providers employ the latest cryptographic protocols and measures to comply with stringent SSL requirements.

The SSL error may also originate from the Certificate Authority’s side if one of its roots or intermediate certificates is compromised. While this is highly unlikely, the CA will swiftly revocate (invalidate) your certificate before its expiration date.

3. Review your ssl installation and renewal. The most common reason you might experience an SSL error is your SSL certificate and how you’ve handled the installation steps. Since there isn’t a universal way to install a certificate for all web servers, missing an important step is easy. Our step-by-step SSL installation tutorials can help you configure your certificate the right way.

Check for a missing intermediate – ensure you’ve uploaded all your SSL files, including the CA Bundle or separate root and intermediate certificates, in the correct order and directory. One misstep could break the SSL chain of trust and leave browsers unable to identify the server.

Renew your ssl certificate on time – an expired SSL certificate error is another preventable rookie error that can harm your reputation and budget. You should always renew your certificate a few days or weeks in advance to avoid unexpected website outages.

4. Enforce HTTPS on all your links and pages. Just as importantly, you must ensure that all your internal links and resources load over HTTPS. That includes images, files, and scripts within your theme and code. Browsers scan for mixed content and flag the website as not secure when the connection goes over HTTP instead of HTTPS.

How to Fix SSL Errors as a Website Visitor?

You can’t do much about a server-side SSL error if you’re a user without backend access. The best action is to contact the website’s administrator and let them know about the issue.

But sometimes, the SSL certificate error will persist on a browser, while other programs will load the website just fine. If this is your scenario, the issue could arise locally from your browser or operating system. Here are the most common SSL errors fixes as a website visitor:

  1. Fix the wrong date on your PC. If your time and date are not synced with the universal Internet time, browsers may mistakenly think that your SSL certificate has expired. Alternatively, the SSL certificate could indeed expire, but your time still runs in the past. To fix this SSL error, you need to adjust your time and set it to update automatically.
  2. Update your browser or OS version. The older browser or OS versions may include unsupported encryption protocols and outdated algorithms. That’s why it’s imperative to keep your systems and browsers up-to-date.
  3. Disable the antivirus software. Your antivirus settings may interfere with the browser or SSL parameters and cause false positives. Try disabling your antivirus and reloading your website to eliminate this potential suspect.
  4. Clear cache and cookies. When you surf the Web, your browser collects and stores all kinds of data like browsing history, website cookies, and local storage. If you don’t clear your cache and cookies from time to time, they may interfere with functionality, including the SSL certificate. It’s always a good practice to clear your browser’s data when encountering an SSL certificate error.

Bottom Line

SSL errors will occur as long as websites use SSL certificates to encrypt sensitive data. Too many variables and systems interact to deliver perfect functionality in a dynamic environment like the Web. Thankfully, many solutions exist for fixing SSL certificate errors.

We’ve tried to amass and present as many types of SSL errors and repairs as possible so you can learn how to deal with them in any situation. The most common questions users ask us are what is an SSL error and how to fix SSL errors. This page provides in-depth answers to both queries.
