AWS Skill, enable a smart home skill with self OAuth 2.0 server

I built an OAuth 2.0 server, and I had verify the implementation of the custom OAuth 2.0 server by postman in chrome, and an nodejs oauth client. It works.

My question is, when I launch Amazon Alexa app in android, and enable the skill. The login UI disappears. It shows nothing. So, I cannot login to get back oauth accessToken.

I use Facebook OAuth service instead now, it works fine. But I still need the custom OAuth 2.0 server to be workable. I doubt it's self-signed SSL certification now, and I will check it in these days.

Any help will be appreciated.

For Self-signed SSL certification, it doesn't work. With a trusted SSL certification, the login UI shows.

Conclusion

After many tests, the custom OAuth 2.0 server for alexa service, must meet following conditions.

  1. The ssl certificate MUST be signed with trusted organization.
  2. The https port MUST be 443, not a custom port. (Ex: 12345)

In some android mobiles, a self-signed certificate or a custom port, the login UI will display. But they all failed at another step for accessToken. The step for authorize is not a problem, but step for token seems to be blocked by alexa app. I suppose alexa app will check the port number, and it doesn't trust self-signed certificate.
