Hi Friends,

Today I am coming with another topic.

As you are looking at the error message getting on the Google Chrome browser.

If you are facing the same message then you need to follow the below steps to resolve the error.

In my case, in the office network, all other machines are working well but only this single machine behaving like this.

In this case, I studied.
I haven’t set any group policy from the Domain controller.
I haven’t set any group policy from the local system.

Then I observed and got the solution is -

the system/server’s date was set to backdated and the region also was changed.
After I set the current date and region then the browser is working normally.

Check the current date and time in the taskbar. Set the current date and time if getting the same error message on the browser.

As you know well, sharing this knowledge -

HTTP : HyperText Transport Protocol.

1. http:// in your address bar in front of the domain, it tells the browser to connect over HTTP.
2. No SSL certificates are required for HTTP.
3. No encryption data in HTTP
4. HTTP is unsecured
5. Port — 80

HTTPs : HyperText Transport Protocol Secure -

1. https:// or https:// in your address bar in front of the domain, it tells the browser to connect over HTTPS.
2. With HTTPS it is required that you have an SSL certificate and it is signed by a CA.
3. With HTTPS the data is encrypted before sending data
4. HTTPS is secured.
5. Port — 443

Have a great day! Enjoy.
