Help with DuoHacker v3

I get a popup saying "Authentication expired, please renew.":

This means that you were authenticated before, but are not anylonger. Take a look into the #info channel on the Discord the find out more.

I get a popup saying "Not authenticated!":

This means that you are and never were authenticated. Use "auth trial" in the #auth-channel on Discord. If you did already, make sure, that you have developer tools open and disabled cache, othwerwise visit https://lolo5.net/apps/duohacker/script.js?t= and add your DuoHacker ID to the url, reload once, then open Duolingo and try again.

Can I renew my trial?

Yes you can, but a payment is required. The trial lasts 24 hours and is Duolingo account specific. This means every Duolingo account can get a free trial. After that you can buy an authentication. The prices are listed in the #info channel on Discord.
