Congratulations ! the worst situation maybe your DNS service provider does not support CAA record .
你的網域 DNS 服務商不支援 CAA記錄設定 .
for example : seed.net.tw , as you can see the picture below , there is no CAA record option to configure .
遠傳(新世紀資通) 根本沒有讓你設定CAA紀錄的地方.

ok , now you can go to find another DNS service. for example , your VPS provider may provide DNS service as well . Good luck ! For me , my hosting provider Linode do provide DNS service , so it’s easy to solve this problem .

login to your linode account and go to [Domain] section
- Create a Domain(that one you want to transfer to)
- copy old DNS record from old DNS server to linode , one by one
- add CAA record

4. in console of your old DNS , change ns servers to new servers , for me , it’s linode’s ns server

for me, it works just 3 mins later, don’t have to wait 24 hours .

if you can not do this way , then you can buy a ssl cert . It’s very easy to do it with namecheap .
In my personal experience , namecheap is very High CP value choice . You can get a SSL and set it up very easy here , click picture below to go .
