Sitecheck Timeout – Tried Everything

Running a WordPress site with Sucuri Plugin, and iThemes Security plugin. It’s a dedicated host and I’m the Sys Admin. Also running Configserver Firewall (CSF/LFD).

I tried disabling iThemese Security, disabling CSF/LFD and SiteCheck Scan immediately fails with a timeout.

Tried chatting with Sucuri to see if they can tell me what operation Sitecheck is trying to perform that results in the timeout and there answer is “I don’t know.” So at a dead end with insufficient information.
