What to Do About the NET::ERR_CERT_DATE_INVALID Error on Chrome?

It is important to act immediately and conduct a thorough investigation when you encounter the NET::ERR_CERT_DATE_INVALID error. The quick fix, which involves closing and relaunching the browser, may work but will not fix the underlying cause of the issue. Moreover, it only works temporarily. Therefore, it’s best to take the bull by its horns and get rid of the cause.

Unfortunately, there are no known causes of the problem. This means it’s a matter of cleaning up your system and freeing it from malware to get rid of the problem. Regardless, tech experts suggest the following tips can help fix the issue:

  1. Disconnect from the current network – If connected to a public network, your connection might not be secure. So, if the NET::ERR_CERT_DATE_INVALID error occurs while on a public network, we advise stopping your browsing session and connecting to a secure network.
  2. Perform a full system scan – Use a professional and trusted anti-malware security tool to detect any malicious content within the system. The security utility can identify malware that might be the potential cause of the NET::ERR_CERT_DATE_INVALID error. As already indicated, it can be a corrupt application or a virus that interrupted with the functionality of the Google Chrome browser.
  3. Remove unknown browser extensions – Usually, adware or malware can add dubious extensions to the browser without the affected user knowing. This is done so that the user’s browsing activities are monitored and vital information captured. Your internet provider or device can sense such behavior and trigger the NET::ERR_CERT_DATE_INVALID error. Therefore, you must go through the list of installed third-party browser extensions and remove them.
  4. Reinstall the Chrome browser – Reinstalling the browser means you are deleting all files that might be corrupt and replacing them with new ones. Although this measure will delete some data, personal preferences can be regained if synched to your Google account.
  5. Configure Date and Time – If your date and time parameters are not set correctly, the NET::ERR_CERT_DATE_INVALID error is bound to happen. So, you must make sure your system’s date and time as well as the region are correctly set.
