How to fix the NET::ERR_CERT_DATE_INVALID error when trying to watch videos?

The NET::ERR_CERT_DATE_INVALID error occurs when a website’s SSL certificate has an invalid date.

This usually happens when the system clock is incorrect or the operating system is outdated, preventing the certificate from being validated.

This error may appear in browsers such as Google Chrome, Firefox, and Edge — especially on older systems, like Windows 7.

First step: test on other devices

Before making any changes, we recommend:

• Test the video on other devices (phone, tablet, another computer)
• Access videos directly on our website: https://pandavideo.com

If the problem occurs only on one device, the instructions below may help you solve it.

How to fix the error on Windows 7

1. Check the system date and time

• Click the clock in the taskbar
• If it’s incorrect, click “Change date and time settings”
• Fix it and confirm with “OK”

2. Clear the browser cache

• Press Ctrl + Shift + Delete in the browser
• Check “Cached images and files”
• Click “Clear” or “Delete”

3. Restart the browser

• Completely close the browser
• Open it again and test the video

4. Check for system updates

• Go to Start > Control Panel > Windows Update
• Click “Check for updates”
• Install everything available and restart the computer

5. Test access on other devices

• If the error happens on all devices, it may be an issue with the website or certificate
• In this case, contact Panda’s support team for analysis

6. Manually update the SSL certificate (last resort)

If nothing works, you can manually import the certificate:

1. Download the certificate from this link
2. Go to:

Control Panel > Network and Internet > Internet Options

3. Open the “Content” tab > click “Certificates”
4. Click “Import” and select the downloaded file
