One such warning which you may have come across while browsing Chrome is HTTPS/SSL Error with the message “Your Connection is Not Private”. The warning will come along with a Red Padlock showing the “Connection is Not Secure”.

Today in this post I will talk in detail regarding this issues and all the potential solutions to fix it. The warning which we generally see are;

Solution 2. Chrome Extension Issue

Open the error generating Web Page in the incognito mode of Chrome Browser.

If the page opens securely in private mode, a Chrome extension is causing the error.

Also, you can go to More Tools > Developer Tools; click on the Security tab.

Step 3. Hit “Details” in the Certificate viewer and select the top certificate (Should be from an address other than the one you were trying)

Step 4. Then hit “Export” and save the certificate file.

Step 5. Go to Chrome Settings → Advanced → Manage Certificates.

Manage Certificate

Manage Certificate

First, check the SSL certificate issuers for the website. Do a Google search and download Root CA certificate of the SSL issuer on your PC.

Then, Go to Chrome Settings → Advanced → Manage Certificates

Here, click on the Intermediate Authorities and import the downloaded Root certificate. This will for sure fix the warning error on Chrome.


Solution 5. Uninstall Anti-Virus Software

If you have antivirus that provides ‘HTTPS protection’ or ‘HTTPS scanning’ then it is preventing Chrome from providing security.

Turn off the AV and if the page loads normally then make the necessary changes to avoid the AV to interfere with the Chrome.

Solution 6. Change Protocol DNS Settings

DNS Server Change

DNS Server Change

Step 1. Search ‘ncpa.cpl‘ in Windows.

Step 2. Look for the option called Internet Protocol Version 4 (TCP/IPv4).

Step 3. Click on it and click on the Properties button.

Step 4. Now manually use following DNS servers; Preferred DNS server as & Alternate DNS server as (Google’s public DNS) (Set IP as automatic)

Step 1. Simply visit the URL ‘chrome://net-internals/#dns‘.

Step 2. Click on Clear Host Cache button next to Host resolver cache.

Step 3. You will notice the websites are working properly.

Step 4. This is one of the easiest and most useful fixes to stop the issue of DNS servers.



Solution 7.  Proceed to Site

If you are not sharing any of your personal details or passwords and just wish to browse through the site then  you can visit the site without any issues;

Advanced → Proceed to Site (Unsafe) → Done

Solution 8. Update the Software

Updating the Chrome Browser and/or Windows Software if available can solve the issue to a great extent.

I recommend you first go with Chrome update – Settings → Help → About Chrome → Update Chrome

Solution 9. Reset the Settings to Default

You can also restore the original Chrome settings and check for the fix

Settings → Advanced → Scroll Down & Reset

Solution 10. Clear History & Data

You can also clear history and complete data of the Chrome Browser. This will help in removing any malicious certificates installed by some bad sites. This would come handy if you are facing issues for some specific sites.

Settings →  Clear Browsing Data →  Select Cookies & Caches delete → Hit Clear Browsing Data

Solution 11. Miscellaneous Methods

If the three methods above don’t work for you then try some other methods listed below.

1. Uninstall Antivirus

Some people reported that after uninstalling their Antivirus program (mostly McAfee) the problem was gone.

2. Disable Your Firewall

Disabling the firewalls may solve the problem as some app may interfere when Chrome is trying to connect. This could be the solution for you too. Disable your firewall and check for the error.

3. Try Connecting in Safe Mode

Boot your computer into safe mode and try to load Chrome. This will help you determine if any third party software is causing the issue as the safe mode will only consist of inbuilt useful files. To do this reboot your computer and hold down the F8 key. Then select Safe mode with networking from the list of options.

    Your guide is more thorough and detailed than most guides I’ve found online on this issue. Thanks!

    I can’t get into Facebook on my laptop because of this error. I’ve tried different browsers, incognito, turning off firewall, re-installing chrome, just about everything I can find and nothing works. It says the certificate expired on 9/24 of this year, and I haven’t been able to get on Facebook since. I tried some of the steps you shared, Solution 3 and 4, but they are different on my computer than what you show. HELP. I have some Facebook business pages and it’s so much easier to update them from my laptop than my phone.

    Thank you so much for this great post, but… if you are not an IT person, and that’s exactly what I am, you would get a bit confused when trying to follow this help. The solution: I found on Fiverr a German guy called Marsarts, who fixed this issue for me very quick and for a very reasonable price, but it’s just me, of course.

    A quick way to bypass this message — open Advanced and see if you have a “proceed to website” option.
    If not, you can try typing “badidea” or “thisisunsafe” directly in chrome on the same page. Don’t do this unless the site is one you trust or develop. The text “badidea” and “thisisunsafe” says a lot!

  7. Cristina says:

    Just change the date& time on your phone. Easy fix. Thank you digitbin for mentioning old browser, that gave me the thought to do that 😊😁👍 Catastrophe averted
