Scatter plot on Dash not showing on heroku

Hey everyone, I am having issues with showing the scatter plot on heroku server. I followed the steps that dash outlayed and I was able to upload the program to heroku, but for some weird reason, the graphs are not being updated. When I run the dash server offline (192…) it works successfully, and then I upload that exact program online it shows the following picture. Am I missing something here?

Also in advance, as a lot of responses to similar forums say that I need to have :Procfile: web: gunicorn app:server … I do have this.

Thank you in advance for any help.

Probably worth checking the logs seeing if there are any illuminating error messages. You should be able to do that with something like heroku logs --tail, can you paste any error messages back here?
