I’ve been experiencing this issue for a few weeks now. This is from Shaw Internet in Winnipeg Manitoba Canada. Included nslookup logs below showing that the issue is with 1.1.1.1 specifically - Google’s DNS for example does the lookup just fine.
There was some small discussion on r/cloudflare on Reddit about a month back, appears some other Canadian users were having issues (Toronto).
I haven’t found any other domains that 1.1.1.1 has trouble with, just VLC’s site.
New users can only have two links in a post, so I’ve had to make some modifications to the below paste.
C:\Users\Jon>nslookup videolan.org
Server: one.one.one.one
Address: 1.1.1.1
*** one.one.one.one can’t find videolan: Server failed
C:\Users\Jon>nslookup videolan.org 8.8.8.8
Server: dnsgoogle
Address: 8.8.8.8
