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

# 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](https://pandavideo.com)

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