Web page view reset?

Ok sorry for the completely beginner question but I put together a dash page of overlays so I could see things in VR, one of them was twitch chat. Was working fine until I tried to login to see if I could access mod tools and now what ever webpage I put in for twitch pop out chat it reverts to the homepage. All other webpages seem to work ok it seems to be only with trying to get to a twitch pop out chat

For example
https://www.twitch.tv/popout/CHANNELNAME/chat?darkpopout
Shows up quick with my name in and the reverts to the homepage, is there anyway to fix this? Almost like I need to clear history or settings or something but really struggling to find anything
