Nevermind, seems it was an error on my cloudflare pointing to an old server perhaps?
In case anyone else has same issue. I found the answer in the cpanel migration thread in a post by Anna. (see below for reference) My cloudflare was pointing to an OLD server I guess.

If you have a custom domain that does NOT use our name servers ( i.e. they use cloudflare, registrars or other service) you need to manually update those with the proper A record (and any other that you need) for the new servers.
x11 = 198.91.81.11
x12 = 198.91.81.12
x13 = 198.91.81.13
x14 = 198.91.81.14
x15 = 198.91.81.15
The old servers are online for backup purposes so you may see what you expect even without the change, but the old servers will be taken offline at a point not too far in the future.
