Follow these steps to troubleshoot and fix a network certificate error:
- Check the time on your computer – To troubleshoot certificate errors, confirm that your computer’s clock is set correctly. Incorrect time settings can cause your machine to authenticate the wrong certificate.
- Check if you're connected to the right network – Make sure that the network you are connecting to is the correct one. Double-check to make sure you are not connected to a public or guest network.
- Check your security software – Confirm that your security software is updated and is not blocking your connection. Depending on your security settings, you may receive warnings when connecting to networks, or you may have to manually respond to the warning to authorize the connection.
- Check the website’s SSL certificate – Check the website’s SSL certificate to see if it is valid. A valid SSL certificate proves that the website is legitimate and can be trusted.
- Check the security of the network – Confirm that the network is secure and that it is not infected with a virus or malware. Make sure you are using the latest version of your security software and that all the necessary security measures have been taken on the network.
