App suddenly not working?

I was creating a multi-page website that recommends new tracks and artists using Spotify API.
Both work, but suddenly the track recommendation page stopped working. After I enter a song title, the page is stuck in a constant running state even though I made no changes to the code. However, periodically the page will spontaneously load.
If I could get some input on this issue I’d greatly appreciate it, thanks.
