Err_cert_authority_invalid on Chrome: Fix this error in under 2 minutes
Keeping your Windows 10 security features updated all the time is recommended if you want to safely complete all your daily tasks.
However, even when all these security recommendations are applied, due to different reasons (which will be detailed during the following guidelines) you might experience some warning messages that might scare you.
And the most common warning related to network connections that aren’t properly secured is the ‘err_cert_authority_invalid’ error.
The message that comes along with this error is the following one: ‘Your connection is not private’. However, that doesn’t necessarily mean you are about to navigate towards a risky website as that might be a general error issued by your web browser or by the Windows 10 system. T
hus, you have to determine what’s causing this warning and, if implied, you need to fix the ‘err_cert_authority_invalid’ error accordingly.
You will get the ‘err_cert_authority_invalid’ warning when the web browser will determine that you are about to navigate towards a website that’s not secured.
Mainly, these websites might not have a SSL certificate, the certificate might not be updated or the server created credentials or certificate which your web browser cannot rely on.
However, sometimes the ‘err_cert_authority_invalid’ error is nothing but a malfunction – you can receive it on all websites or on pages that you know for sure that are secured.
Therefore, you need to find the perfect solution to fix this issue. Since in most cases the ‘your connection is not private’ message is prompted when using Google Chrome, we will focus on listing the troubleshoot steps for this particular web browser.
How to fix err_cert_authority_invalid errors
Here are 5 solutions that you can use to get rid of err_cert_authority_invalid Chrome errors for good:
- Check Date and Time settings
- Adjust antivirus settings
- Disable extensions on Chrome and reset settings
- Clear history on Chrome
- Assign DNS Settings
You’ll find the detailed step-by-step instructions below.
1. Check Date and Time settings
As a security measure, Chrome and all the other web browser clients will let you access webpages only if the Date and Time is set properly.
If, for some reason you rolled back the time or the date on your Windows 10 computer you will receive the ‘err_cert_authority_invalid’ error each time you will try to access a page through internet.
Therefore, you should start the troubleshoot initiative by setting up the date and the time.
2. Adjust antivirus settings
Usually, the ‘err_cert_authority_invalid’ error is caused by your antivirus program. That’s why, before applying more complex solutions, you should make a few changes within your antivirus internal settings.
Now, depending on each program these tweaks might be different, so the important thing is to get the main idea: you need to turn off ‘HTTPS Scanning’ or the ‘HTTPS protection’ feature.
Here are a few examples of how you can complete this task:
- Click on Settings and go to Privacy Control.
- Switch to Antiphishing tab.
- From there set Scan SLL to Off.
- Depending on the BitDefender version you might have to follow this instead: go to Protection, choose Web Protection and turn off Scan SSL.
- Launch Settings and choose Active Protection.
- Then, pick Web Shield and choose Customize.
- The Unable HTTPS Scanning option must be unchecked.
- Navigate to Settings.
- Click on Extend and select Network Settings.
- From there you should have several options related with the SSL scan.
- Choose the one that lets you navigate on all browsers.
3. Disable extensions on Chrome and reset settings
- Open Chrome and click on the Menu icon (located at the upper right corner).
- Click on More tools and choose Extensions.
- Turn off all installed Extensions and then reboot Chrome.
- Go to Settings again, scroll down and pick Show Advanced Settings.
- Under Privacy you need to uncheck the ‘Send a Do Not Track request with your browsing traffic’ option.
- From Advanced Settings also click on Reset Settings – the option is located at the bottom of that page.
- Restart Google Chrome after applying all the tweaks from above.
- If Chrome gets stuck, you can use this guide for fixing it.
4. Clear history on Chrome
Along with disabling extensions you should also clear your web browser history and associated cache. Here is how you can do this process on Chrome:
- Once more, access Chrome’s Settings.
- Scroll down and pick Advanced Settings.
- Select Clear Browsing Data.
- From the pop-up that will be displayed select the fields from the list and when done select ‘Clear browsing data’.
5. Assign DNS Settings
The problem might also be related with the DNS settings and it can be addresses by following:
- Click on the Cortana icon and use the Search box for entering Network and Sharing Center.
- From the left sidebar then choose Change Adapter Settings.
- Right click on the Adapter that’s currently active and choose Properties.
- Pick Internet Protocol Version 4 and then select Properties.
- Click on ‘Use the following DNS server address’ and type Google’s Public DNS servers: 188.8.131.52, respectively 184.108.40.206.
- Apply settings and restart your Windows 10 machine.
