cPanel Addon Domain - Long DNS Resolution Spike

Hi Folks,
I’ve been having an issue with my cPanel Addon Domain recently. I’ve first noticed there was periods where the site would refuse to load (constant loading spinner in the browser). If I disabled Cloudflare it would instantly load and even re-enabling Cloudflare again would cause it to be fine until usually the next day.

My primary domain does not experience this.

Yesterday I activated the Cloudflare Speed Metrics Insights for the domain. I checked it this morning and noticed a very large (>8000ms) spike in DNS loading at one interval. I’d imagine this is the problem.

However, I am unsure if it’s Cloudflare related or origin server related. Whenever the issue occurs my Primary Domain and other Addon Domains continue to load perfectly fine.
