There seems to be a recent issue of compatibility with Plarium and my chromebook lap top. 

This message never used to appear. I first bought my chromebook so I could have a computer when I worked as an over the road trucker for 8 months. I used my cell phone as a hot spot, and used my lap top for mapping routes, getting on forums I post on, and yes, continuing to play this game. That was about 2 1/2 years ago, and up until recently this chromebook lap top worked like a charm for playing vikings. 

Now, I continue to get the "Authorization has been denied for this request" message when trying to log on. It seems to work in private browsing mode, but will not work in normal mode. I thought there was something wrong with my chromebook so I bought another one thinking maybe this one is just getting old, and I have the same problem with the brand new one. 

Luckily I have a PC which I also play on and everything works fine on it, which leads me to believe, with 2 chromebook lap tops having this issue when trying to log on to Plarium, and my PC working fine, that there is some kind of strange compatibility issue going on that might have occurred with a recent update.
