How can I allow users to login to Spotify for my streamlit app?

I’m creating a python app that allows user to login to spotify and see their stats (top artists, songs, etc). The app works from my laptop (when not in incoginito mode), but no from my phone or from any other device
My app is deployed on Community Platform: https://spotifystats.streamlit.app/
This is the github repo: GitHub - juansuero/wrapped2.0
Whenever an user clicks the spotify button, there is an error message that says: accounts.spotify.com refused to connect.
