SSL certificate errors and how to fix them

An SSL certificate is a standard security technology for encrypting information between a visitor's browser and their website. Because it helps keep confidential information such as passwords and payment information safe, Visitors feel more secure on sites that are encrypted with SSL. You can identify HTTPS encrypted sites in their URLs and the padlock icon in the address bar.

SSL Certificate Unreliable Error

This error indicates that the SSL certificate is signed or approved by a company that the browser does not trust.. That means that the company, known as the certification authority, is not in the browser's built-in list of trusted certificate providers or that the certificate was issued by the server itself. Certificates issued by the server are often called self-signed certificates.

Name match error

This error indicates that the domain name in the SSL certificate does not match the URL that was entered in the browser. This message can be caused by something as simple as “www”. Let's say the certificate is registered for and type Then you will get SSL certificate name error.

Mixed content error

This error indicates that a secure page (one that is loaded with HTTPS in the address bar) contains an item being loaded from an insecure page (one that is loaded with HTTP in the address bar). Even if there is only one insecure file on one page (often, an image, marco, Flash animation or JavaScript snippet), your browser will display an error message instead of loading the page

SSL certificate error expired

This error occurs when the site's SSL certificate expires. In accordance with the requirements established by the Certification Authority Forum / Browser (CAB), SSL certificates cannot have a lifespan of more than 27 months .

Suppose you have chosen a plan that includes SSL certification or installed a certificate on your site. Then open Google Chrome and try to visit a page on your site and, instead of loading, receive a message

Diagnose the problem with an online tool.

To start, use an online tool to identify the problem causing the SSL certificate error on your site. You can use a tool like SSL Checker , SSL Certificate Checker o SSL Server Test , which will verify that an SSL certificate is installed and has not expired, that the domain name appears correctly in the certificate and more. To use the tool, just copy and paste your site address into the search bar.

Install an intermediate certificate on your web server.

If the problem is that your SSL Certificate Authority is unreliable, then you may need to install at least one intermediate certificate on your web server. Intermediate certificates help browsers establish that the website certificate was issued by a valid root certification authority.

Update to a dedicated IP address.

If you receive a name matching error, then the problem may be your IP address

If you still receive a name matching error, you may need to get a wildcard SSL certificate. This type of certificate will allow you to secure multiple subdomain names, as well as your root domain. For example, could get a multi-domain SSL Certificate.

When you type your domain name in your browser, first connect to the IP address of your site and then go to your site. As usual, a website has its own IP address. But if you use a type of web hosting other than dedicated hosting, your site may share an IP address with multiple sites. If one of those websites doesn't have an SSL certificate installed, then a browser may not know which site it is supposed to visit and displays a mismatched name error message. To solve the problem, you can upgrade to a dedicated IP address for your site.

Change all urls to HTTPS.

If you get a mixed content error on one of your web pages, Copy and paste the URL into to identify insecure items. Once you have identified the elements, edit the source code of the page and change the URLs of insecure items to HTTPS.

Renew your SSL certificate.

If your SSL certificate has expired, you must renew it immediately. The details of the renewal process change depending on the web server or certification authority you are using, but the steps remain the same. You will need to generate a CSR, activate your certificate and install it.
