I'm trying to activate a new dev kit, Flex 2, and I get stuck with HTTP error 499.
Please help.

I got the same error as yours when I received my Flex Dev kit. What I do is:
1.logging in https://sandbox.dev.clover.com/
2.Go to Dev Kits on the bottom left.
3.Associate Dev Kit. And enter Flex serial number which you get on the 499 screen.
4. After that just hit back on the Flex. It will finish the set up
