\ud83d\udc49 In this post, we’ll take a closer look at the ERR_SSL_PROTOCOL_ERROR issue<\/a> and discuss its main causes. We’ll also show you how to fix it<\/a>. Let’s get started!<\/p>\n<\/div>\n\n\n\n When you create a website, you’ll need to install a Secure Sockets Layer (SSL) certificate<\/a>. This enables the site to run on a secure protocol, known as HTTPS<\/a>.<\/p>\n\n\n\n An SSL certificate ensures the secure transfer of data between the user’s browser and the server the website is hosted on. In fact, if a site does not have this certificate, the browser will probably display a warning or return an SSL error message<\/a> like ERR_SSL_PROTOCOL_ERROR.<\/p>\n\n\n\n Even if a site does have an SSL certificate, you might still encounter this error. This can be due to an outdated cache or a glitchy extension in the user’s browser. Alternatively, a firewall or anti-virus program on the user’s device might be blocking the connection.<\/p>\n\n\n\n In some cases, the ERR_SSL_PROTOCOL_ERROR issue is caused by a problem on the website rather than the user’s device. For example, the SSL certificate might not have been installed or configured correctly.<\/p>\n\n\n\n Sometimes, the certificate is properly configured, but the website is still running on the HTTP protocol (the unsecure version of HTTPS). If your site is using HTTP instead of HTTPS, search engines like Google will deem it unsafe, which could lead to a drop in rankings.<\/p>\n\n\n\n The good news is that these issues should be easy to resolve. \ud83d\ude0e<\/p>\n\n\n Now, let’s look at some effective ways to resolve the issue, starting with the easiest fix.<\/p>\n\n\n\n As mentioned earlier, this error could be caused by an issue with the user’s browser or device. If you’re encountering the ERR_SSL_PROTOCOL_ERROR message when trying to access your site, the first thing you want to do is clear your browser cache<\/a>.<\/p>\n\n\n\n This is because the browser could store old data about the SSL certificate. Therefore, it’s unable to authenticate a secure connection.<\/p>\n\n\n\n To clear your browser in Chrome, click on the three dots in the top-right corner of the browser and select More tools<\/strong> \u2192 Clear browsing data<\/strong><\/em>. This will open a window:<\/p>\n\n\n Here, you can choose your preferred time range (we recommend All time<\/strong><\/em>) and the cached data you want to delete. In this case, you only need to check the box for Cached images and files<\/strong><\/em>.<\/p>\n\n\n\n When you’re ready, click on Clear data<\/em><\/strong> and try to visit your website again. If you’re still getting the message, the problem might be on the server rather than your device. However, just to be sure, you’ll want to disable any browser extensions and firewalls and try again.<\/p>\n\n\n If there are no issues on your end or you’ve certified that the ERR_SSL_PROTOCOL_ERROR message is displayed to anyone who visits your site, there might be an issue with your SSL certificate. <\/p>\n\n\n\nWhat is ERR_SSL_PROTOCOL_ERROR?<\/h2>\n\n\n\n
