I have to wait 30 odd seconds before my browser brings anything up.... it didn't start to do this until about a week or so ago after one of the previous patches.
Not sure if it's a Steam or RO2 issue. I'm guessing it's a steam issue, since my steam browser does the same thing, but it only seems to be happening to my Tripwire games (Ostfront/Killing Floor)
But if you give it 30 seconds or so and then hit refresh the browser seems to work normally.... it might even take up to a minute, but once it snaps out of it's fit, you can hit refresh constantly and it responds perfectly again..... it just seems to be at startup.
