1. Examine\/Check Your SSL Certificate<\/h3>\n\n\n\n

After that, the tool will take a couple of minutes to process and scan your site\u2019s SSL\/TLS configuration on your web server.<\/p>\n\n\n\n

2. Check the Non-Encrypted Version<\/h3>\n\n\n\n

Try to use a non-encrypted version of this site if there is one (the address of such a site begins with HTTP, not HTTPS). In many cases, it can help. However, many modern browsers do not allow the opening of unprotected websites.<\/p>\n\n\n

<\/hr><\/div>\n\n\n

3. Update Your Operating System<\/h3>\n\n\n\n

If you are using an outdated operating system such as Windows XP, then we recommend installing a more modern version of the operating system. Ideally, it should be the latest OS with the updates.<\/p>\n\n\n\n

4. Try Firefox Browser<\/h3>\n\n\n\n

To work with problematic websites, try using the Firefox browser. The latest versions use their own encryption library. The most important, that it opens websites with the described error without any problem.<\/p>\n\n\n

5. Clean your browser history or cache<\/h3>\n\n\n\n

When you use a web browser to visit websites, it saves some information that includes things like the pages you visited, images, and other files from those websites in the form of a cache.<\/p>\n\n\n\n

The browser keeps this data so that when you revisit a website, it can load it faster by using the stored information instead of downloading everything again. <\/p>\n\n\n\n

However, keeping an old cache for a long time can be a problem. Sometimes, the websites you visited make changes to their system and update their content. If your browser still uses the old cache, it might not show you the updated version of the website. This can cause issues like SSL errors, which are related to secure connections, and it can also create security risks.<\/p>\n\n\n\n

To avoid these problems, it’s a good idea to regularly delete your browser’s web history and cache.<\/p>\n\n\n\n

If you are using Chrome browser, follow the steps given below:<\/p>\n\n\n

<\/hr><\/div>\n\n\n

Step 1:<\/strong> Depending on your browser, Go to the settings menu. <\/p>\n\n\n\n

In Google Chrome, for example, you can find the settings menu by clicking on the three vertical dots located in the upper right corner of the window.<\/p>\n\n\n\n

Step 2:<\/strong> To proceed, select \u201cMore tools\u201d and then click on \u201cClear browsing data\u201d.<\/p>\n\n\n\n

Step 3:<\/strong> A pop-up window will be displayed, and you can choose all three options located under the “Basic” section as depicted in the picture below. These options consist of “Browsing history,” “Cookies and other site data,” and “Cached images and files.<\/p>\n\n\n\n

Step 4:<\/strong> Click on \u201cClear data<\/strong>\u201d to initiate the process.<\/p>\n\n\n\n

<\/div>\n\n\n\n

By doing so, any corrupt or invalid information stored locally in your browser will be completely erased. This ensures that if it was causing the authentication issue, it won’t occur again.<\/p>\n\n\n\n

6. Check SSL configuration with Cloudflare<\/h3>\n\n\n\n

If there is a misconfiguration between your SSL settings and Cloudflare, the “err_ssl_version_or_cipher_mismatch” error may be triggered. If this is the issue, the SSL checker tool will show the certificate as invalid.<\/p>\n\n\n\n

However, you can resolve this issue by simply configuring SSL (The specific configuration steps may vary depending on the type of SSL) via the Cloudflare dashboard.<\/p>\n\n\n\n

If you have installed a Free SSL certificate from Cloudflare, then you need to configure the SSL setting from the Cloudflare dashboard itself.<\/p>\n\n\n\n

Note:<\/strong> WPOven Provides Free SSL with every wordpress agency hosting<\/a> plan.<\/p>\n\n\n\n

1. Log in to your Cloudflare account.<\/p>\n\n\n\n

2. Click on the SSL\/TLS option at the top of the dashboard.<\/p>\n\n\n\n

7. Go to the Configuration tab.<\/p>\n\n\n\n

8. Look for the Purge Cache section at the top and click on the Purge Everything button.<\/p>\n\n\n\n

9. Wait for a few minutes, and then go back to your website to check if the issue has been resolved.<\/p>\n\n\n\n

7. Try Disabling QUIC Protocol<\/h3>\n\n\n\n

Disable the QUIC protocol in the Google Chrome browser. In the address bar, enter chrome:\/\/flags\/ . After opening the protocol settings, select Disabled from the top and click the Restart button below.<\/p>\n\n\n

8. Reset Chrome Browser Settings<\/h3>\n\n\n\n

\n
\"Reset<\/a>

<\/div>\n\n\n\n

Restart the Chrome browser. If the issue still persists, try and uninstall the Chrome browser and restart your computer. For better results, you may even use the special uninstall tools. After that, download and install the latest version of the browser.<\/p>\n\n\n\n

Earlier in some of the older versions of the Chrome browser, there was a temporary solution, in which the user could enter chrome:\/\/flags<\/strong>, find the Minimum SSLv3 version support feature, and set it to SSLv3. <\/p>\n\n\n\n

In more recent versions, the developers have developed the feature. Now, users can check whether they are able to fix the issue using this option on their browsers.<\/p>\n\n\n

10. Try Disabling Antivirus Temporarily<\/h3>\n\n\n\n

Temporarily disable your antivirus and try to visit the problem site. It is because, some antivirus applications create a layer of their own certificates between your browser and the web, as a result, it triggers this kind of issue.<\/p>\n\n\n\n

11. Try using an older version of TLS<\/h3>\n\n\n\n

If you are a webmaster of this site, try changing the server settings to use TLS 1.2 instead of RC4. Also, activate TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256. Why is that important not to use RC4? It deleted the RC4 support in the Chrome browser later than the 48 version. So, as not to lose visitors, remove it from your website.<\/p>\n\n\n\n
