There is some problem between archive and cloudflare DNS, I see people complain about it daily on this site. Here is how you fix it if you are not using cloudflare DNS and are still getting the error (and are using firefox):

1. Firefox settings -> type dns in search bar

2. Under DNS over HTTPS either turn it off or alternatively select NextDNS as provider in the increased protection box.

3. archive today should start working now

What FF version ? No issues here, I'm on 102 ESR
