Twitch Extension Authentication via JWT and shared secret

[BarryCarlyon]

@BarryCarlyon

And your frontend passed up the correct token (the authToken not the helixToken)

Then the other thing to do is to check that the recieved variables on your server are what you expect.
And check the time on the recieving server is accurate.

After that theres not many other things it could be unless you have a second extension and loaded in the wrong extension secret

Did you check/try these other steps?
