NET::ERR_CERT_DATE_INVALIDRan into the NET::ERR_CERT_DATE_INVALID
error and not sure what to do? This error usually pops up due to issues with SSL certificates or your computer’s date and time settings. Don’t worry, we’ve got seven straightforward solutions to get you back on track.
1. Conduct an SSL Check
The first thing you should do is check the website’s SSL certificate. An SSL certificate is like a passport for a website; it needs to be valid for secure communication.
Detailed Steps to Check SSL Certificate:
- Navigate to SSL Shopper
Go to SSL Shopper’s SSL Checker. - Enter the Domain
In the “Hostname” field, type the website’s domain you’re having trouble with, and then click ‘Check SSL’. - Review the Results
If you see green check marks next to each category, the SSL certificate is valid. If not, the certificate is either expired or invalid.
2. Clear the SSL State
Old SSL certificates can sometimes cause the NET::ERR_CERT_DATE_INVALID error. Here’s how to clear them:
For Windows Users:
- Open Search Box
Press the Windows key + S together. - Type ‘Internet Options’
Click on the ‘Internet Options’ that appears. - Go to Content Tab
Here, you’ll find a button that says ‘Clear SSL State’. Click it.
For macOS Users:
- Open Spotlight Search
Press Command + Spacebar. - Type ‘Keychain Access’
Open the application. - Locate SSL Certificates
In the left panel, click on ‘Certificates’. - Remove Old Certificates
Look for any certificates marked with a red X, right-click, and choose ‘Delete’.
3. Check Your System Date and Time
Incorrect system date and time can also cause the error. Let’s correct it:
For Windows Users:
- Open Start Menu
Press the Windows key. - Type ‘Change the Date and Time’
Click on the setting that appears. - Toggle ‘Set Time Automatically’
Make sure this is turned on. If it’s already on, toggle it off and on again, then click ‘Sync Now’.
For macOS Users:
- Open Apple Menu
Click on the Apple icon in the top-left corner. - Go to System Preferences
Choose ‘Date & Time’. - Check Automatic Settings
Make sure the ‘Set Date and Time Automatically’ checkbox is checked. If it’s unchecked, check it.
4. Clear Browser Cache and Cookies
Old cache and cookies can interfere with SSL certificates. Here’s how to clear them:
For Google Chrome Users:
- Open Chrome
Launch Google Chrome. - Click on the Three-dot Menu
It’s at the top-right corner. - Choose ‘Settings’
Scroll down until you see ‘Privacy and Security’. - Click ‘Clear Browsing Data’
A new window will pop up. Check the boxes for cookies and cache, then click ‘Clear Data’.
5. Temporarily Deactivate Browser Extensions
Sometimes, browser extensions can interfere with SSL certificate validation. Here’s how to identify the problematic extension:
- Open Incognito Window
Press Ctrl+Shift+N (Windows) or Command+Shift+N (Mac). - Test the Website
If the website works, an extension is likely causing the issue. - Go to Extensions
Open a normal window, click on the three-dot menu, and choose ‘Extensions’. - Deactivate Extensions
Toggle off each extension one by one and test the website each time to identify the problematic one.
6. Disable VPN and Antivirus Temporarily
Sometimes, VPN and antivirus software can interfere with SSL certificate validation. Here’s how to disable them temporarily:
- Locate Software Icon
Find the VPN or antivirus icon in your system tray (Windows) or menu bar (Mac). - Right-click to Disable
Usually, a right-click will give you options to disable the software. Choose to disable it temporarily. - Test the Website
Try accessing the website again to see if the issue is resolved.
Note: Make sure to enable your VPN or antivirus software after testing.
7. Change DNS Servers
Changing your DNS servers can sometimes resolve the error. Here’s how:
For Windows Users:
- Open Control Panel
Search for it in the Start menu and open it. - Go to ‘Network and Sharing Center’
Click on it. - Choose ‘Change Adapter Settings’
It’s usually on the left panel. - Right-click Your Connection
Choose ‘Properties’. - Double-click ‘Internet Protocol Version 4’
Choose ‘Use the following DNS server addresses’ and enter 8.8.8.8 and 8.8.4.4.
For macOS Users:
- Open Apple Menu
Click on the Apple icon in the top-left corner. - Choose ‘System Preferences’
Then go to ‘Network’. - Select Your Connection
