Auth0 not working when I host my React app


I am having some trouble connecting Auth0 with my hosted React app. I run it on my local server and it works great but once I try it on the deployed site in Netlify gives me the below error message and the deployment fails. It seems to happen just after I select the login button. Any tips? I have the URL below as well. Any help would be greatly appreciated! Let me know of any other info I can give to make this easier. Thank you!

Error message:

" This site can’t be reached
undefined ’s server IP address could not be found.

Site link:

Hmm, seems you’ve renamed or removed the site since you wrote in. I would be happy to try to take a look if you could tell me where it lives now?
