How to Fix ‘This Connection Is Not Private’ Error

You’re in high spirit to land something fantastic in search engines, yet run into a “This connection is not private” error message. Isn’t it annoying?

There’s no doubt about that. It must frustrate your surfing experience. Not to mention you’re blocked from desired content. This might come across as urgent if you’re chasing the information available on a preventable page only.

Frankly, “This connection is not private” is a common error that most Internet users hit at least one time, but many of them don’t even know why this happens and how to fix it. That’s why this article comes up.

We’ll introduce you to what a private connection error is, why it appears, and how you can troubleshoot it on your own.

What is “This Connection is Not Private” Error?

First, every secure HTTPS website owns an individual SSL certificate. Standing for Secure Sockets Layer, SSL is a data security protocol that generates an encrypted link between a web server and a web browser.

Once you’re trying to access a website, your browser sends a request to your hosting server, asking for certificate approval. Your server will validate if the target site’s certificate is up to current privacy standards.

If the certificate set up is incorrect, data will not be encrypted properly. That’s when the browser fails to verify whether the site is safe to visit. In this regard, it pops up a warning message to inform you of the issue.

Some users are frightened about this error; however, it’s not really a big deal. Your browser is just trying to prevent you from accessing an insecure site; otherwise, your personal data could be susceptible to online threats.

Avoid Public Wifi

Believe it or not, you’re more likely to encounter a private connection issue in a public network. Simply understand, the issue arises since public wifi doesn’t run over secure HTTPS, but HTTP instead. When you perform a transaction on a public connection, your information is not encrypted properly. That’s why the browser shows up a warning message.

Besides, this error should occur when you’re trying to access an HTTPS site before signing in a portal’s terms and agreements. If that’s the case, here are some easy tips to bypass it.

  1. Connect to a public Wifi
  2. Open a window and run through a non-HTTPS site like http://example.com
  3. Here’s a sign-in page showing up. You’ll need to accept the terms and then log in. Once signed in successfully, you can browse to the site run over secure HTTPS as normal.
