Constantly Loading on Authorize

[taddmtii]

I am using Flask/Python to develop my own web app using Spotifys web API. OAuth/Spotify client requires me to sign in multiple times (everytime I make a change to my python file). Everything was working thus far, but now I am encountering an issue where for about 16 hours I have not been able to authorize myself into my hobby app (named FlowFinder). 

I tried using a different browser, incognito tab, new client id and secret, changed callback function etc...
