I have deployed the VM using your vagrant script.
NGINX is accessible on port 80 - 8080
Apache is also accessible on port 81 - 8081
NGINX Python is also accessible on port 82 - 8082
But MapProxy is NOT accessible on port 83 - 8083
Seems you have missed something on MapProxy configuration/provisioning
Mille Grazie !
