The irritating SSL connection errors may suddenly appear from nowhere, or maybe the result of lousy SSL certificate setup. No matter what the reason is, you surely don’t want your visitors to see any kind of dangerous warnings when surfing your website. These browser notifications can be: “Your connection is not private“, “Your connection is not secure”, “The site’s security certificate is not trusted”, or “This site is not secure”, “Secure connection failed”, and so on, depending on which web browser they are using.

It indicates there is no way to establish a secure connection with the website’s server. These warnings bring visitors an awful user experience. Furthermore, they are a serious threat to your website and online business’s integrity, which makes visitors leave in droves if you don’t handle this issue.

Bellow, you will discover the most common SSL connection errors, as well as methods on how to handle and get rid of them quickly.

Untrusted SSL Certificate

Nowadays, most web browsers have a built-in feature to determine whether root SSL certificates are trusted. These SSL certificates are issued by regulated Certificate Authorities (CA), or also known as root authorities. When a user visits a secure version of a website, which begins with HTTPS, their web browser will immediately validate the SSL certificate. Suppose the web browser figured out an SSL certificate that isn’t signed by one of the trusted “root authorities”. In that case, it will display one of the SSL errors mentioned above to warn the user about an insecure connection.

In fact, most root authorities don’t sign website certificates directly for security purposes. They deploy an “intermediate certificate” for the purpose of creating a “chain of trust” to the root. More clearly, the root SSL certificate is used to sign the intermediate certificate, and this certificate will be used to sign the website’s SSL certificates. That said, the missing of an intermediate SSL certificate or the presence of a self-signed SSL certificate are two major causes of SSL connection errors.

Missing Intermediate SSL Certificate

Installing an SSL certificate for a website requires the necessary knowledge to avoid mistakes, which inevitably lead to SSL connection errors. A proper setup should display the chain of trust that the web browser will use to validate the SSL certificate. The root certificate from root authorities has signed the intermediate certificate, which is used to sign the SSL certificates for websites.

Depending on the types of SSL certificates, there will be appropriate installation guides out there. For example, if you use a free SSL certificate from Let’s Encrypt, let’s follow these instructions to get things done perfectly. However, if you purchase a premium SSL certificate from SSL providers, it’s better to ask them for installation guides.

Self-Signed Certificate

Anyone can create and sign an SSL certificate using website software.
