Hosting (whitelightningfilms.wpmudev.host) Domain pointing setup issue

Hi,

I have been trying last few days to setup whitelightingfilm.com domain pointing to WPMUDEV hosting server I setup on whitelightningfilms.wpmudev.host. account

whitelightningfilm.com domain located at GoDaddy, I added following config within GoDaddy DNS records;

Type Name Value TTL Actions

A @ 209.97.143.72 1/2 Hour

AAAA @ 2a03:b0c0:1:e0::48e:2001 1/2 Hour

CNAME www @ 1/2 Hour

During adding of whitelightningfilm.com had option to also add http://www.whitelightningfilm.com, which I selected after few minutes once SLL cert showed green and everything looked good, I try to set it as primary domain, recieve following error message;

"Oops, there was an error when trying to change the primary domain for whitelightningfilm.com. (Internal Server Error: Please try again or contact support if the issue continues.)

Note: the DNS records on GoDaddy also live as my friends website currently hosted there, in process of changing over to WPMUDEV.

BR,

Steven
