I have the same issue, but without Tor. For me it comes from using Cloudflare/1.1.1.1 as my DNS Resolver. Apparently they've been beefing with archive.is over some dns implementation specifics for some time.
I think some Cloudflare guy replied to a question about that on HackerNews some time back: https://news.ycombinator.com/item?id=19828317
