Verifying Keap server/domain in Facebook ads/business suites

Hi there,
This is sort of a moot note since I’ve been surreptitiously banned from advertising on Facebook. But I wonder if one of the issues causing the block is that the Keap server domain associated with my ad account was not verified. Does anyone know about this or run into this issue before? How would one verify that domain? Can I put pixels on my Keap Landing Pages?
Thanks for any insight.
