CMG Woes

Hello all,

Looking for some advice please for some issues I'm facing with my CMG.

My setup:

Hybrid Joined

Co-Manged

Boundaries setup via AD sites.

Public cert provided by cloudflare

DNS and CName all fine

In ccm messaging log, I am seeing entries like

IsSslClientAuthEnabled - Determining provisioning mode state failed with 80070005. Defaulting to state of 1216.

Post to https://CMGNAME/CCM_Proxy_MutualAuth/72057594037978093/ccm_system_windowsauth/request failed with 0x87d00231.

[CCMHTTP] : WINHTTP_CALLBACK_STATUS_FLAG_INVALID_CA is set

In location services log

Failed to send management point list Location Request Message to CMGNAME/CCM_Proxy_MutualAuth/72057594037978093

Failed to get AAD info from CMG with error 0x87d00231, Status Code 0, StatusText

Failed to get CMG metadata 0x87d00231

I've obviously done a search for these errors but found nothing helpful.

Any help would be appreciated, as I'm starting to see a few issues with devices.

Thanks in advance.
