Fix “Your connection is not private” error message in Google Chrome

troubleshoot “Your connection is not private” error message



Spread the love
Reading Time: 4 minutes

Just a few minutes back got this error message. The message is related to an unsure security certificate which means this error message usually appears on the secured website ( Secured websites are the ones which requires a username and password to log in.)

Here is the error message
Your connection is not private. Attackers might be trying to steal your information from somewebsitename (for example, passwords, messages or credit cards).

On clicking the Advanced button,
This server could not prove that it is; its security certificate is supposedly from 0 days in the future. This may be caused by a misconfiguration or an attacker intercepting your connection.
Proceed to  (unsafe)

NET::ERR_CERT_DATE_INVALID

You can click on proceed link which is unsafe. But chances are you may not be able to log in.

How to fix “Your connection is not private” error

  1. Check the date and time

This is the most common reason for the error message popping up in most machines. Secure websites are very sensitive. To issue a valid certificate to browser their websites, they check date and time in your machine. If it doesn’t match the correct time and date in your location, the website prevents further interaction with such machines for security reasons.

In my case, the error message was as a result of the wrong time and date. The CMOS battery which helps BIOS remember date and time even when the machine is turned off was damaged. As a result, I have to manually enter the right date and time every time I turn on my computer. The error message popped up when I forgot to update date and time. The permanent solution, in this case, was to replace faulty CMOS battery.

  1. Disable security software and check if the problem gets fixed

Security software is the second most possible culprit that might create this problem. Either the security software is corrupted or a particular feature is responsible for the problem.

READ  How to start Windows 8.1 in Safe Mode

Try the below steps in this order.

  • Most security software now carries an SSL or https scan feature. Check if you can find that feature under settings or advanced features. If that feature is not working properly, it might cause the error. Disable this feature and check if the problem gets fixed.
  • If the problem is still not fixed, disable the security software. Now check the problem status. If disabling security software worked, then you need to reset security software settings to default settings or re-install the security software properly.

Avast, Kaspersky, ESET etc all have SSL scanning features. Recently a wrongly configured Avast SSL scanning was responsible for the problem in a lot of computers using the software. Sometimes small malware prevention software can also create this problem. Some website ad prevention software or add-on can also create this problem.

  1. Check and clean Google Chrome browser

Browse the website using another browser like IE, FireFox, Edge, Opera etc. If it works fine in other browsers, this should be a problem with Chrome. Try the steps below.

  • If you just want to clean the Chrome browser, go to Settings -> Scroll down to show advanced settings -> Click Clear browsing data under Privacy options.
  • If it is still not working, scroll down further under settings and go to Reset settings. This will reset chrome to original browser settings.
  • An easy way to clear the junk from browsers is to run the free tool Ccleaner. Here is how to run Ccleaner like a pro. It not only cleans the junk from browsers, but also from your computer.
  • Use Chrome Incognito window and check if the problem gets fixed. In the Incognito window, all third-party extensions and add-ons are disabled by default. If the problem is with a corrupt browser extension or add-on, you won’t have any problem in Incognito window. Once confirmed, remove the corrupted third-party extension.
  • If none of the above worked, uninstall Chrome and then re-install the latest version with all updates installed.

  1. Clear DNS cache

This step should clear if there are any corrupted DNS records inside the computer. This should also fix minor problems with IP and DNS settings.

READ  All you need to know about Internet Cookies

Open the command prompt with admin rights. Type the following commands in the order

  • ipconfig /flushdns
  • ipconfig /registerdns
  • netsh int ip reset c:\resetlog.txt
  • netsh winsock reset
  • Restart the computer and check the status.

  1. Register dll files to fix corrupt files

The above steps should fix most problems. You may try this extra step just to make sure the files related to secure websites are working properly. The step below will register the important dll (Dynamic Link Library) files which should fix the certificate error.

  • Open the command prompt with administrator privilege.
  • Copy the list of command listed below.
  • Then right click on command prompt window, click on paste. This automatically initiates the registering of dll files in the background. Wait for a minute or two to make sure all files are being registered.
  • Once it is over, check if the problem is solved.

    please help me thanks

      • Anup Raman May 12, 2017, 7:05 am

        Please remove all security software including Zemana AntiMalware and HitmanPro. Then check if the problem is solved. You can always re-install the software once the problem is fixed.

    Hi.
    Im staying at a hotel right now with free WiFi.
    My android phone works fine using the hotel wifi, but the laptop doesn’t. The error you posted above shows up.
    With the laptop I have to use my existing mobile WiFi.
    I wonder if it’s possible that a laptop shows error for a WiFi connection, the same WiFi connection that works well with an Android phone?
    And for the same laptop to work with one WiFi connection and not the other???
    Thanks

    • Anup Raman September 25, 2016, 1:38 pm

      This is a problem between Laptop and hotel provided Wi-Fi as everything works fine with mobile Wi-Fi.

      Try Step 1 and Step 2 as valid steps for your laptop problem.

      If it is not fixed, try the next step.

      Open the command prompt with admin rights. Type the commands steps in this order.
      ipconfig /flushdns
      netsh winsock reset
      restart computer and check the status.

      If the problem is not fixed, try the next step.

      Press Windows Key + R. In the run window, type ncpa.cpl. This will open network connections
      right click local area connection, then click properties. (If it is wireless connection, right click on Wireless Network Connection)
      Select Internet protocol version(TCP/IPv4), then click properties
      Select internet protocol ,select “use the following DNS server address”
      change DNS server address to global DNS value given below
      Preferred DNS: 8.8.8.8
      Alternate DNS: 8.8.4.4

      Restart laptop and check the status.

    Correcting date and time. Easy fix Thanks!

  • Sarrah August 9, 2015, 12:40 am

    hii.. I tried everything that you had listed above but it still doesn’t work . i keep getting the error saying “xxx.com normally uses encryption to protect your information. When Chrome tried to connect to xxx.com this time, the website sent back unusual and incorrect credentials. Either an attacker is trying to pretend to be xxx.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Chrome stopped the connection before any data was exchanged.

    You cannot visit xxx.com right now because the website sent scrambled credentials that Chrome cannot process. Network errors and attacks are usually temporary, so this page will probably work later.”
    I don’t know what to do. Please help me.

  • Lucky August 3, 2015, 4:59 am

    it works perfectly!! well done…
    Thanks a lot..

  • wayne May 6, 2015, 7:38 pm

    After two day of trying to fix this I found out that the time zone on my router was set to west coast time rather then east coast time..Now it works fine!

  • Young Kim March 14, 2015, 5:47 pm

    I put in correct date/time, it worked.
    Thank you.
