Twitch API Down?

I’ve got two websites that both use Twitch to authenticate users logging in, both are not working at the moment and I’m getting:

Array
(
[error] => Internal Server Error
[status] => 500
[message] =>
)

Is there an issue with twitch? Or has the new Twitch API v5 killed off the old code?

https://barrycarlyon.github.io/twitch_misc/authentication/implicit_auth/ is working fine

as are a number of my other tools

Authentication is neither New API or v5.

And you would get a 4xx error not a 5xx error.

5xx could be a number of things. Depends which call is generating the 5x
