Admin page returns not found 404 on azure but not on local

System Information
  • Strapi Version: 3.6.2
  • Operating System: macOS
  • Database: Azure Database for PostgreSQL flexible server
  • Node Version: 16.1.0
  • NPM Version: 7.11.2

I’m running strapi from a docker container. When I deploy my image locally I can access the admin gui. However, when I deploy the image to an azure container instances service the /admin route just returns 404 not found. What could possible be wrong?
