Authorization doesn't work after uploading API

I have a C# Web API that is using Auth0 for authorization, and while I can call to private routes when I run my front and back end applications locally, after I upload it, I get a 401 error. Why is this happening? The only difference between local and uploaded is that I have my web page use different environment variables when I build the project, with “appUri” and “appUri” pointing to my web domain. My back end app uses the same Auth0 settings for domain and audience.
