ITVX (itv.com) Won't let me access any shows; Error 01-01

[Atsuji-Chan 0]

Hello! This is my first post here. I'm trying to access ITVX, ITV's streaming service to watch some shows, however I keep getting error 01-01 on their site when trying to watch stuff. From some googling this appears to be VPN related. I tried a handful of different browsers and cleared cache/cookies and them, trying to follow the advice of different people with similar issues. one Reddit poster from, 5 months ago mentioned they had success with Express VPN which gives me hope that this is just some configuration issue I can fix with Eddie. I have tried going through all the different UK Servers with no success. 

Please let me know your suggestions, or if you need more information about my setup

Thanks!
