Well, OpenVPN simply tries to do what the system tells it to do. In a world where IPv4 and IPv6 coexist, if a hostname is associated with both an IPv4 and an IPv6 it is expected that both can provide the same services and that he client will decide, based on its own logic, what to do.
In this case OpenVPN is trying IPv6 first because that is what iOS provides first. Why having an AAAA record for your hostname if you don't want clients to use it? ISn't it just better to have a A record only so that everybody will always get an IPv4 only?
I don't think OpenVPN Connect can be restricted to IPv4 only.
