I got the same error when I entered this url and went to subsequent pages:
https://social.msdn.microsoft.com/forums/azure/en-US/home?category=windowsazureplatform
That category resulted in about 65 or so forums, accounting for the long url. I would email fissues [at] Microsoft [dot] com, with the above url and explain that you get an error when paging.
Edit: I emailed the forum admins at fissues. Waiting for reply. Forums may have been added to that category recently. I think there are 69.
