Reddit is blocking users based on user agents?

Started to get this message when accessing Reddit. I use LibreWolf as a browser, which does indeed provide a more generic user agent to combat fingerprinting, but nothing out of the ordinary either (Mozilla/5.0 (Windows NT 10.0; rv:109.0) Gecko/20100101 Firefox/119.0). Anyone else experiencing this?

Edit: seems to have resolved itself. Thanks for confirming I wasn't doing anything wrong. Let's hope this isn't some new algorithm to test if for insufficient fingerprinting so Reddit can kick ad-resistant users.
