Australia

### Description

ABC iView experiences a 401 authentication error when downloading the webpage. I have tried this on two systems. The other is using the June 6 2022 FFmpeg build and the verbose log is from my main system using the May 26 2022 build. I have been using NordVPN to access the content and I have been able to view the videos from Chrome. I have tried all NordVPN locations and using the NordVPN DNS server. I am using the latest build of Windows 11. Part of me wonders if the fake IP that is used by DLP was blacklisted by iView as I have been able to get DLP to work only a couple of times in the past two weeks. iView did recently require accounts to view content that is not a livestream. The link that I tried is a livestream. The livestream is available outside of Australia without a VPN which makes me think the IP has been blacklisted even more.
