PFX Certificate Connector error 0

Hi,

I am trying to install a certificate on computers managed using PKCS certificates with Intune.
I did all the steps as in the guide here:

https://video2.skills-academy.com/en-us/mem/intune/protect/certificates-pfx-configure

The computers get the ROOT CA successfully, but the second certificate they fail to install.
