Internet users regularly encounter many errors when trying to access various Web sites. From browser errors to database connection errors, server errors to operating system errors, your computer screen displays various error messages for different types of errors.
NET::ERR_CERT_DATE_INVALID is one such error message that appears for the following reasons.
- There is a problem with the date and time on your computer. That is, the date and time are incorrect.
- Your SSL certificate has expired.
- An SSL certificate was issued from untrusted sources, as most browsers recognize SSL certificates installed by trusted certificate authorities.
This error also appears in a different form. The error message “Your connection is not private” has the same meaning and means the same reason: Chrome cannot securely load a website, which is why it displays this error message. Sometimes incorrect settings cause this error as well.

Keep your browser up to date
Google Chrome is one of the most popular web browsers out there. However, many users are still stuck with older versions of the software. This could be because the browser is outdated or you haven’t installed the latest version. To make sure you’re running the latest version, follow these steps:
1. Open Control Panel.
2. Click “Uninstall a program.”
3. Select Google Chrome and uncheck the box next to “Keep my files,” then click “Remove.”
4. Restart your computer.
5. Reinstall the browser and check if the error persists.
You might want to recheck the Google Chrome plugins
There are many different kinds of Secure Sockets Layer (SSL) certificates, and each type of certificate has its own set of errors. These errors can range from a simple warning to something much worse. If you see one of these errors, it could mean something wrong with your browser plugins.
In some cases, the plugin might be working fine, but there could be another problem that causes the plugin to stop working. You’ll want to make sure that you’ve installed all of your plugins correctly and that everything is functioning normally.
If you still aren’t able to load the site, try disabling your extensions and re-enabling them one at a time until you figure out which extension is causing the issue. Once you know which extension is causing the trouble, you can go into your settings and disable it. This way, you won’t accidentally enable it again later and cause problems.
Temporarily disable your anti-virus and firewall
Antivirus programs are one of the most critical tools used to protect computers against malware infections. However, sometimes it happens that antivirus scans cause errors while you browse the web. This issue occurs because some antiviruses use the HTTP protocol to check files downloaded from the internet. In such cases, the browser gets confused and displays a warning about a security risk. You might want to turn off the antivirus scan temporarily until the problem disappears. To do so, follow the steps mentioned below:
1. Open Control Panel.
2. Click System and Security.
3. Select Programs and Features under Administrative Tools.
4. Uncheck the box next to “Windows Defender.”
5. Restart the computer.
6. Reinstall the antivirus program.
Use Google DNS instead of your current DNS server
1. To change your DNS server, open the Settings app and select the network icon.
2. Select the Wi-Fi option and scroll down to find the name of your current connection.
3. Tap it once to select it, then tap the gear icon next to the name.
4. Scroll down again and tap Advanced options. In the list that appears, look for the DNS tab.
5. If there is no DNS tab, tap Add a New Setting. This opens the screen shown above. Tap the IPv4 setting and enter 8.8.8.8 as the value. Then tap Save Changes.
6. Your device will now use Google’s Public DNS servers, which are faster than the ones offered by your ISP.
SSL cache should be cleared
If you are getting NET ERROR CERTIFICATE DATE INVALID errors while browsing the Internet, it could be due to having outdated SSL certificates stored in your browser. If that’s the case, clearing the SSL cache might help. Here’s how to do it.
Open up your web browser and go to the address bar. Type in inetcpl.cpl and press Enter. Then, select the Content tab. Select Clear SSL state. This will clear out your old SSL certificates. You can now access the sites normally again.
You may need to change your Internet connection
Sometimes your connection is not private – an error cert date invalid occurs because you’re connected via an insecure Wi-Fi or other networks.
In such a case, your browser displays a warning about it. This error usually happens when you try to access a site over HTTP while connected to a different network. You might see a “Connection Reset” warning in Chrome or a “Your connection is not private” warning in Firefox.
To fix this problem, change your Internet connection. If you’re still getting the same issue, make sure you’ve set up HTTPS correctly.
Ensure that your PC has the correct date and time
When setting up your computer for the first time, it’s essential to make sure that the correct time and date settings are selected. If you don’t, you might see an SSL certificate error. This happens because the server doesn’t recognize the time and date on your machine. You’ll want to fix this issue before moving forward. Here’s how to do it.
1. Open the Control Panel via the start menu.
2. Click on “Clock and Region.”
3. Select “Date & Time Settings” and select “Set Automatically.”
4. Make sure that the correct time zone is selected.
5. Set the correct time and date.
6, Restart your browser and try again.
