Bug needs fixed! (Incompatible with Cloudflare DNS Servers)
This is allegedly resolved in firmare version 42056 (viewtopic.php?f=10&t=23390&sid=b3779d8c ... ead1647b8e), but I have version 450992 and still see the issue. Thankfully, I found this thread (viewtopic.php?f=5&t=21640&sid=db30b3b6d ... a&start=20) and ended up working around it by setting my primary DNS to 1.0.0.1 (still Cloudfare), then secondary/tertiary DNS to Google's servers. This seems to work well so far since 1.1.1.1 is the problem DNS.
