Unable to register the Fire TV device using its DSN

Vega Open Beta Q&A
1

I am attempting to set my Fire TV Stick 4K to developer mode by following the instructions at:

https://developer.amazon.com/ja/docs/vega/0.23/run-apps.html#ftv-tab

I am logged into my developer account and have signed into the Fire TV Stick using the same account, but I do not know where to enter the DSN.

https://community.amazondeveloper.com/t/cannot-register-fire-tv-stick-select-for-developer-mode/25285

I also referred to this Q&A, but

For a workaround, please go to this URL directly: Amazon Developer Sign-In

When accessing the URL, it redirects to

https://developer.amazon.com/ja/kepler/open/developer-mode/devices

resulting in a 404 error .

Hi @mariko,

Welcome to the Amazon Developer Community!

Thank you for reporting this issue with the device registration process.

The DSN registration interface is embedded directly within the Vega documentation page. When you are signed into your developer account, the registration widget should appear on this page under “Step 2: Register your Fire TV device for Developer Mode”: Vega仮想デバイスまたはFire TV Stickでのアプリの実行 | Design and Develop Vega Apps

If the registration interface is not loading on that page, please try the following:

  1. Sign out and sign back into your developer account at https://developer.amazon.com
  2. Clear your browser cache and reload the page
  3. Try accessing the English version of the same documentation page: Run Your App on Vega Virtual Device or Fire TV Device | Design and Develop Vega Apps

Please let us know if this resolves the issue.

Thanks for helping us improve the Vega platform.

Warm regards,
Aishwarya

I was able to register!

It seems the main issue was that my browser’s preferred language was set to Japanese.
This caused a redirect to the URL with “/ja” appended, preventing the input field from appearing.
When I changed my browser’s preferred language to English and accessed the specified URL, the redirect did not occur, and the input field was displayed.

Thank you for your assistance.
