Hello and thank you for your fast reply but i am sure that this is an issue.
The best and faster solution after spending a couple of hours is to
1. Create a domain into another user and issue the certificate normally.
2. Convert the domain to a user account with SSL support
On that way you will have the domain working normally in a few minutes.
I am sure that CWP team will find a solution for the issue.
Hope that was helpfull
