:(

Well, Vietnam is not in the list of restricted territories.

Anyway, what is "your region" ?

Is this where I am now, or is it where I activated my Oculus 2 five years ago ?

Same in Argentina. It's almost surely a region whitelist for now (it's the only reason Argentina ever gets blocked).

Can’t you just use VPN?

Your Meta account profile region has to be in the U.S., and they do Geo IP and SMS verification.

Same in Canada. lol
