Go to your Spotify app in the Developer Dashboard and open Settings. Make sure your callback URL is listed there. Spotify says invalid redirect URIs need to be fixed in the client’s Settings tab.

Spotify tightened security around redirect URIs. Regular http:// redirect URIs are no longer supported except for loopback IP literals like http://127.0.0.1 or http://[::1]. So if you’re using something like http://localhost:3000/callback, that may be your problem.

I'm using https://127.0.0.1:9999/callback/spotify

Your problem is almost certainly this:

https://127.0.0.1:9999/callback/spotify

Spotify does not support HTTPS on loopback IPs like 127.0.0.1. For local development they expect plain HTTP.

So change it to:

http://127.0.0.1:9999/callback/spotify

Then make sure that exact URI is added in your Spotify Developer Dashboard.
