409 or 504 error when uploading a Vagrant box to the Vagrant Registry

Hi there!

I’ve started to receive 409 and 504 HTTP errors when trying to upload a Vagrant box with slightly more than 5 GB to the Vagrant Registry.
For context, I build a Vagrant Box using Packer and upload it to the Vagrant Registry using the “vagrant-registry” post-processor.
I’m pretty sure I’ve managed to upload Vagrant boxes with more than 5 GB in the past.

Did someone hit the same limit recently?
Is it a known limitation of the Vagrant Registry?
