Can no longer archive webpages

Description of the issue:
Brave browser is deemed ‘unsupported’ or ‘out-of-date’ by certain websites. Previously I encountered this problem mainly with privacy-unfriendly websites such as those owned or hosted by Google LLC, Alphabet Inc and Facebook Inc, but now it has started making its way over to websites like archive.today.
When I try to visit any of the archive.today mirrors (including their onion mirrors via Brave’s Tor-mode), I get the following screen:

Exact URL of the website in question:

  • archive.today
  • archive.is
  • archive.vn
  • archive.md
  • archive.li
  • archive.fo
  • archive.ph
  • archivecaslytosk.onion
  • archiveiya74codqgiixo33q62qlrqtk​gmcitqx5u2oeqnmn5bpcbiyd.onion

Did the issue present with default Shields settings?
Yes

Does the site function as expected when Shields are turned off?
No

Is there a specific Shields configuration that causes the site to break? If so, tell us that configuration.
No

Does the site work as expected when using Chrome?
Supposedly, but I don’t know. Maybe somebody who has Chrome can verify, because I’m not installing that spyware to find out.

Brave version:
Brave 1.13.82, Chromium: 85.0.4183.83 (Official Build) (64-bit)
