Hello,
After a lot of work with my Host. They have said I should Host my Domains my Old Account & DNS on there, but A Record to Point to my New Server 
I have dun this with the Base Domain & 2 Subs . Which 1 IP Points to 1 IP (A) & the other Points to the Second IP (A) on the New Server , works fine. Now I have put DNS for a Sub on Second IP on New Server SOA has New Second IP & A also , but it dose Not Resolve . Any thoughts as to what I might be doing wrong ?
I’m at my wits end 
Thank-You
Hi
sounds like your host (registrar???) has directed you to (keep) using their DNS. THEY are authoritative and your HESTIACP DNS records are not being used (works for the two domains because you have added the A records… give your domain(s ) subdomains to check this further…
IF my guess is right you need to modify/add DNS records at the host for each subdomain to point to the respective IP…
IMHO it is best to make use of the built in DNS capability of HESTIACP…to avoid this kind of problem…
cheers
PS: even if you add records on the host… keep in mind that it may not resolve until TTL…
