Hello there, I have the same error. do you have any solution for this?

Can you show me your cloudmgr log? Are there any errors there?

Hi Prajwal,
kind of strange...there is no error in cloudmgr.log but error:
Configuration version of the CMG service should be 2.
Failed to get CMG service metadata. Status code is '401' and status description is 'CMGService_Invalid_Client_Certificate'...................

what version of SCCM are you using? Are you using HTTPS PKI or are you using eHTTP? Is your trusted root certificate imported in the CMG properties? Did you configure the bindings in IIS to use the certificate for https?

I am running SCCM in 2002. I am using PKI external wildcard certificate and Trusted root certificate imported from my domain properties.
I try to follow your instruction SCCM CMG https://www.prajwaldesai.com/setup-sccm-cloud-management-gateway/
I don't see anything about using IIS binding. do we need to configure IIS binding?
much appreciate your help.
