Your connection is not private alert

As of July 2008, Google started to mark websites that do not have an SSL certificate and do not use the https protocol as unsafe in the Chrome internet browser. Along with this situation, browsers with a wide range of usage such as Microsoft Edge, Mozilla Firefox, Opera and Safari started to apply this security principle.

However, websites that no longer have SSL certificates and do not use the https protocol will be marked as insecure in red and even “Attackers may be trying to steal your information from example.com.” It also tried to drive visitors away from the site by displaying a phrase such as:

https protocol and SSL certificate

SSL (Secure Sockets Layer) certificates are a product that checks the accuracy of site addresses and ensures that data is transmitted securely by making data communication between two points over an encrypted channel. An SSL certificate is a digital certificate that authenticates a website and provides an encrypted connection. SSL stands for Secure Sockets Layer, which is a security protocol that creates an encrypted connection between a web server and a web browser.

HTTP stands for “Hyper Text Transfer Protocol”. The HTTP protocol is the protocol that allows viewing web pages over the network. HTTP protocol determines the exchange rules between client (PC) and server (server). Https is the version of http with an SSL certificate attached. It aims to establish a more secure communication by encrypting the communication between the website and the visitors. Thus, attackers will have difficulty in intercepting the communication between the server and the visitor.

First of all, it is worth noting that; How you get the connection error messages is important for solving the problem. For this, it is important whether you get the Connection error on only one site or many sites.

If you only get the connection privacy error on one site: This issue is not related to your computer or device you are using. The problem is with the website’s SSL certificate running out or not. If you wish, you can inform the website about this problem.
If you are getting this error on many sites: we can say that the problem is related to the device you are using or the network you are connecting to. Continue reading the article for the solution to your problem.

Make sure your device’s time is correct

If your system time is wrong, secure communication between the server and the website will not be activated. That’s why you may see an error message like NET::ERR_CERT_DATE_INVALID. This error message says that your system clock is incorrect. In this case, you should immediately correct your system clock. If your system clock is running late, you may need to replace your bios battery. To change your watch:

Right click with the mouse on the time and date in the lower right corner of the taskbar.
Then click “Set date and time”.
Set or synchronize the time manually.

Force open site (Not secure)

There is an “Advanced” button on the bottom left side of the warning you receive an error. Click here.
Then click the “advance to site.com (not secure)” link that appears at the bottom.
You will reach the site from an unprotected route.

Clear the DNS cache

DNS is the system that converts the domain name of the websites you enter to the ip number. When you want to visit these websites again later, the web browser stores these DSNs in cache. You can try to fix the problem by clearing the DNS cache. For this: How to Clear DNS Cache? Flush DNS Server Cache

Clear your browser’s history

If you think there is a problem with the browser, by clearing History and Cookies; most of the time, it can provide solutions to browser problems. To clear the history of the Google Chrome browser:

Then go to the History option. Or you can open the history section by clicking the Ctrl+H keys together on the keyboard.
Then click on “Clear browsing data” option.
Select the time range “All time” and clear the data.

Restart your device

Some instabilities in the system may cause some errors. For this, it can be useful to restart our computers and devices regularly. Especially in Windows operating systems, there is a system called fast startup, which saves the session when shutting down the computer and enables it to boot up quickly on the next startup. This quick start system can cause problems over time. It can be helpful to restart your computers regularly for this.

Use a different browser

If you are getting this issue in a browser, we can find out if the problem is in the browser, on my site or on the network by installing and trying a different browser. For this, install a different web browser immediately. Alternatively you can use web browsers:

If the problem is only experienced in your network, unplug your modem and plug it back in after 2 minutes.
