I have set up my new domain with Yola and am attempting to point my previous domain (hosted by Melbourne IT) to Yola. I have set up two A records so that the Hostname (ns1.secure.net and ns2.secure.net) both point to 184.108.40.206 (the IP address advised by Yola). But when I try to add the Melbourne domain to my Yola account, I get the message that "Your domain is not pointed at Yola". I have waited 48 hours for this to take effect (the TTL is actually set to 3600). What have I not done?
