Object Store Subdomain "Unauthorized"

I've just setup and object store, and in OVH's control panel it tells me to add a CNAME for BAR.auth-10286efc0d334efd917d476d7183232e.storage.uk.cloud.ovh.net:

I've done that, but both the CNAME value and the subdomain just take me to a page that says "Unauthorized", what's up?

http://store.bar-rts.com/

I have same problem!
Container URL worked, but subdomain with CNAME said “Unauthorized”
