I've been fighting this for hours and hours now, and I just cannot figure out what's going wrong.
I'm working on an Alexa Home Skills app. I have the authorization URL setup, and that loads properly. But as soon as I redirect, I get the error message, "An error occurred while attempting to link Alexa with the external provider."
I've dug through the forums here and seen that a lot of people run into trouble with SSL validation. So I switched my Access Token URI to another server, signed by a different CA. Still, no luck.
I've quadruple checked every variable, value, url, and path that I can find. Everything looks right, but obviously I'm doing something wrong.
Is there some way I can figure out what the error actually is? I'm totally stabbing in the dark at this point.
