ISE Integration pxGrid Root CA Error

[dantignac]

I have a new implementation of Cisco DNA I'm working on without our VAR or Support (right now.) I'm trying to integrate ISE and I See this error below:

I've tried to apply the same Root CA in DNAC and ISE. I've been fiddling with the Root CA on the ISE node I'm connecting to with DNAC. The certs both match but still something isn't right. Is it all the nodes with pxGrid needing a Root CA cert?

Version:

ISE 2.7 Patch 2

DNAC 2.2.3

I'm wondering if any has seen this issue and seen a resolution.

I am seeing this same issue with my DNAC and ISE deployment. ISE version 3.0 patch 5 and DNAC version 2.2.3.3. Nobody seems to know what the issue is.
