Hello RolandLin,
Since there is no information about the error or description of the cause, the best recommendation is to directly open a ticket from the Partner Center, so the Microsoft Technical Team can review the submission and provide more information, as well may provide how to resolve it.
Access to Partner center: https://partner.microsoft.com/en-us/dashboard
Once logged in the Dashboard, click on the ? icon on the top right, and chose "Technical Support"
