When I enable the skill on alexa app, It redirects me to the third party login page, after being successfully logged in it gives an error "an error occurred while attempting to link Alexa with the external provider. Please try again”. In the developer console, I can see authorization URL being called, after that code and state is returned back, but then instead of calling Access Token URI, it displays this error. Is there anyone who found the same issue? or anyone who know what might be going wrong?
