Amazon Alexa skill: We were unable to link xxxx at this time. And with 401 Unauthorized.
===================================================================
Skill model: CUSTOM
Skill STATUS: In Development
Account Linking: Auth Code Grant
Client Authentication Scheme: "HTTP Basic" (Credentials in request body is the same error)
Default Access Token Expiration Time: 360
1，Use Browser on Microsoft Windows open https://alexa.amazon.com/spa/index.html
In "DEV SKILLS", Enable my CUSTOM skill, Amazon Alexa service accesses my "Authorization URI" and asks for the "code". I send the "code" to it's redirect_uri(https://pitangui.amazon.com/api/skill/link/xxxxxxxxxxxx).
https://pitangui.amazon.com/api/skill/link/xxxxxxxxxxxx?state=xyz&code=SplxlOBeZQQYbYS6WxSbIA
This is no problem.
2，Amazon Alexa service has received my "code" and use it to access my "Access Token URI".
(Note that the authorization server must respond to the token request within 4.5 seconds.)
Yes, I'm sure it is accessing my "Access Token URI", because the code it provided is the same with that I sended in Step 1.
HTTP/1.1 401 Unauthorized Server: Server Date: Thu, 09 May 2019
And in my Browser, URL: https://skills-store.amazon.com/external/link-result?success=false&languageCode=en_US&skillId=amzn1.ask.skill.29bba2e6-8c01-4cd1-975d-xxxxxxxxxxxxx&skillStage=development

Can anyone help me? Thanks!
