I don't know what you mean by that. But, you still have an AAAA record in your DNS for this domain name. And, IPv6 connections using that address still fail. If you don't have a way to reliably test IPv6 you should remove the AAAA record.

Your DNS
patrick-hove-construction.co.za. 0 IN A 161.97.69.237
patrick-hove-construction.co.za. 0 IN AAAA 2a02:c207:2243:9511::1
Both of these IP addresses are for Contabo. You just don't have the correct IPv6 address or something else in your config needs correcting for IPv6. You may wish to speak with Contabo about that.
Once you get this sorted some or even all of your other problems will go away.
