Bypass for the certificate must be valid for 825 days or fewer
A quick workaround of you are using Google Chrome is to use the bypass word &quot;thisisunsafe&quot;:

Go to the (trusted) page
Once you get to the message that says &quot;Your connection is not private&quot; click anywhere on the page
Type: thisisunsafe

This will add your page to a whitelist of the browser and instantly bypass the warning. Don't do this on sites you don't trust.
