flyctl fail: lookup api.fly.io: i/o timeout

I’m trying to start using fly.io, but I’ve been getting this error for the last 2 days.

$ flyctl auth login
Error Post "https://api.fly.io/api/v1/cli_sessions": dial tcp: lookup api.fly.io: i/o timeout

The api is responding ICMP:

$ ping api.fly.io

For me, it looks like some network issue. Possibly firewall or any geographical restrictions… I’m trying from a brazilian IP. Can it be helped?
