CloudFlare's proxying & the 1Password SCIM bridge

I'm looking for a definitive answer to the question "Is there any way to use CloudFlare's proxying with the 1Password SCIM bridge?" From my own personal experience, all signs seem to point to "no", but surely there must be a way? Any time I've enabled proxying on the SCIM bridge's `A` record, it always causes trouble with the `certificate-manager`, which results in certs not being renewed, which then causes the bridge to stop working completely. So is proxying completely out of the question? Or is there some way to get it working?

Thanks!
