Receiving 404 Error in Heroku with Django-Tenants with Wildcard CNAME - django

Question

I have a really weird situation I cannot seem to figure out. I have not touched my implementation of this package since the beginning of the year and now the functionality ceases to exist on my live heroku server. I currently have a Create Account form on my public tenant which generates a tenant/domain just as the docs do and django-tenants does its auto schema generation. This works correctly on my localhost and have zero problems. However on my live server, I proceed to get a 404 error... Not Found...The requested URL / was not found on this server.
​
I have a CNAME record on DNSimple which points to a wildcard domain that appears to be working, because I have already have a tenant I made awhile ago that is still completely functional (ie. some-customer.mydomain.com). I have looked into my PSQL db attached to heroku and everything is there as it should be, as well as the migrations occurring in the logs when I create an account which generates a tenant.
​
I was hoping that there might be some enlightenment as to what I am doing/have done wrong to make this issue occur. It just seems so odd that none of my now generated tenants can be accessed via their Domain.

Everything seems to look fine. If you try generating a tenant using the django-tenant docs in the shell on your production server by doing heroku run python manage.py shell -a yourapp and that works, then there is something wrong with your code that generates the tenants which you have not posted.
