Ah, I see the probable cause of the problem.  
You’ve ping’ed the `api.[mydomain].org` and it should return a IP address, but it couldn’t resolve the host. This means it’s a DNS problem. It can’t reach the server because it doesn’t know which server to talk to.

And after the `dig` commands, the problem is definitely your DNS. You’ve set the following DNS:

```auto
api.[mydomain.org] IN CNAME api.[mydomain].org

```

The CNAME record is just something like: For this domain (`api.[mydomain].org`), use the same DNS configuration as the value IP (in this case also `api.[mydomain].org`. So it’s pointing to itself, which stays in a constant loop.

What I like to do when setting up openBalena, is creating a subdomain like:

```auto
balena.[mydomain].org

```

And setting all my `A` (IPv4 of the server) and `AAAA` (IPv6 of the server) records to that subdomain. Setting up openBalena with that domain, so:

```auto
./scripts/quickstart -U <super_username> -P <super_user_password> -d balena.[mydomain].org

```

And setting the DNS CNAME’s like this:

```auto
api.balena.[mydomain].org IN CNAME balena.[mydomain].org
registry.balena.[mydomain].com IN CNAME balena.[mydomain].org
vpn.balena.[mydomain].com IN CNAME balena.[mydomain].org
s3.balena.[mydomain].com IN CNAME balena.[mydomain].org

```

You’re probably ready to set-up your devices now!  
Also, it could take up to 72 hours for DNS changes to take effect. This is almost never the case and depends on what you’ve set-up in your DNS, but it could take a while.
