Hi,
How did
you generate certificate? The proper process could be the following steps:
1.
Create certificate request via Certificate Wizard or Cmdlt.
2.
Send Request to CA to ask them to issue certificate for you.
3.
Receive certificate from CA and then install it.
Note: Click ”Complete Pending Request” to install.
4.
Assign services to certificate.
