Alexa skill problem

Subject: Alexa skill fails during account linking (accountLink/establish?...error=1) after server selection

Hi,

I'm trying to set up the official Emby Alexa skill and have reached a point where I believe I've ruled out the usual configuration issues.

Environment

• Emby Server 4.9.5.0

• Synology DS220+

• Emby Premiere active

• Google Pixel 10 (latest Android)

• Latest Alexa app

• Reverse proxy with a valid HTTPS certificate

What works

• Remote access works correctly.

• I can connect to the server through app.emby.media.

• Emby Connect works normally.

• Alexa discovers my server correctly.

• The server appears in the skill and can be selected.

Failure

After selecting the server, the browser redirects to Amazon's account-link endpoint, which always ends with:

.../api/v1/accountLink/establish?...&error=1&showRedirect=1

The page displays:

"Please proceed by clicking the button below."

After clicking the button, it returns to Alexa, but the account is never linked.

Important observations

• A new authorization token is generated on every attempt, so this does not appear to be a stale authorization issue.

• The failure always occurs at Amazon's accountLink/establish step.

• The Emby server log shows no Alexa- or Amazon-related requests during the failed linking attempt. It appears the callback never reaches the Emby server.

Troubleshooting already completed

• Disabled and re-enabled the Alexa skill.

• Waited several minutes before re-enabling.

• Corrected the Emby Connect email associated with my Emby user (this fixed server discovery).

• Verified reverse proxy configuration.

• Verified the HTTPS certificate.

• Verified remote access.

• Confirmed the server is discoverable by Alexa.

• Confirmed the issue reproduces consistently.

At this point it appears the failure occurs before the Emby server is contacted.

Is there additional logging that can be enabled for Alexa account linking, or is this a known issue with the current Alexa skill or Amazon's account-linking flow?

Thank you.
