Discover why NordVPN couldn’t validate your TLS certificate, troubleshoot the issue, and prevent it from happening again.
Causes of TLS Certificate Validation Issue
Incorrect System Time
Having an incorrect system time on your device can lead to TLS certificate validation issues. This is because TLS certificates have a validity period, and if your system time is not accurate, it may mistakenly flag a valid certificate as expired. To prevent this issue, always ensure that your device’s system time is set correctly.
Expired Certificate
Another common cause of TLS certificate validation problems is using an expired certificate. Just like a carton of milk, TLS certificates have an expiration date. If you try to use a certificate that has expired, your system will reject it, causing validation errors. To avoid this issue, make sure to regularly renew your TLS certificates before they expire.
Incorrect Certificate Chain
TLS certificates are issued in a hierarchy known as a certificate chain. Each certificate in the chain verifies the authenticity of the one above it, ultimately leading to a trusted root certificate. If there is a mistake in the certificate chain, such as a missing or incorrect intermediate certificate, your system will struggle to validate the TLS certificate. To prevent this issue, always verify the certificate chain before installing a TLS certificate.
In summary, the causes of TLS certificate validation issues can range from simple mistakes like having the wrong system time to more complex issues like an incorrect certificate chain. By understanding these common causes, you can take proactive steps to prevent these issues and ensure smooth validation processes.

Troubleshooting Steps
Check System Time
When encountering TLS certificate validation issues with your NordVPN software, one of the first troubleshooting steps you should take is to check your system time. Incorrect system time can often lead to validation problems with certificates. Your system time should be synchronized with the correct time to ensure that certificates are being validated accurately.
To check your system time on Windows, simply right-click on the date and time in the lower right corner of your screen and select “Adjust date/time.” On Mac, you can find the option to adjust date and time in the System Preferences. Make sure that your time zone is correct and that your system time is accurate.
- Check system time settings on Windows
- Adjust date and time on Mac
- Ensure correct time zone is selected

Preventing TLS Certificate Validation Issues
Regularly Update System Time
One of the key factors in ensuring the smooth validation of TLS certificates is to regularly update your system time. The accuracy of your system’s time plays a crucial role in verifying the validity of certificates, as any discrepancy can lead to issues with validation. By keeping your system time up to date, you can avoid encountering errors related to expired certificates or incorrect validation.
Renew Certificates Before Expiry
Another important step in preventing TLS certificate validation issues is to renew your certificates before they expire. Certificates have a set validity period, and failing to renew them in a timely manner can result in validation errors. By proactively renewing your certificates before they expire, you can ensure that your connections remain secure and free from any validation issues.
Verify Certificate Chains before Installation
It is essential to verify the certificate chains before installing any new certificates on your system. Certificate chains establish the trustworthiness of a certificate by linking it to a trusted root certificate. By verifying the certificate chains before installation, you can confirm the authenticity of the certificates and prevent any potential validation issues from arising.
In conclusion, by regularly updating your system time, renewing certificates before expiry, and verifying certificate chains before installation, you can effectively prevent TLS certificate validation issues and ensure the security of your connections. Remember, proactive measures are key to maintaining a secure and error-free environment for your online activities.
