Frequently Asked Questions
What does NET::ERR_CERT_DATE_INVALID mean?
This error means that the security certificate presented by the website has an issue with its validity period. It might be expired, not yet valid, or your system's clock is out of sync, making the certificate appear invalid.
Is it safe to proceed past this error?
Proceeding past this error is not recommended because it means your connection to the website is not secure. Your data could be intercepted by attackers, compromising your privacy and security. Only proceed if you fully understand the risks and trust the website implicitly, or if you are certain the issue is with your local system clock.
Why does my system clock affect website security?
Website security certificates have specific validity dates. If your computer's date and time are incorrect, your browser may incorrectly perceive a valid certificate as expired or not yet valid, leading to security warnings like NET::ERR_CERT_DATE_INVALID.
Can a VPN cause this error?
Yes, in some cases, a VPN can interfere with certificate validation, especially if it routes traffic through servers with incorrect time settings or if it performs its own SSL inspection. Temporarily disabling your VPN can help determine if it is the cause.
What if the website itself has an expired certificate?
If the website's SSL certificate is genuinely expired or misconfigured, there is nothing you can do on your end to fix it. The website administrator must renew or correct their certificate. In such cases, you should avoid submitting sensitive information to that site.
