After clicking “Login and generate Refresh & Access Token,” I was redirected to an HTTPS address like https://192.168.1.155/spotify.php?code=..., which was inaccessible. Changing it manually to http made it work.
Steps to reproduce
- Go to Spotify settings
- Click the token generation button
- Page fails to load over HTTPS
Expected behavior
Be redirected to a local page that loads successfully.
Suggestion
Use http:// instead, or support HTTPS with a valid local certificate.
