vCloud director 5.1 Organizations issue

Hello,

I am setting up the cloud using vcloud director 5.1, while adding / Importing VAPP in the organization I am getting "Unable to complete the operation because the current Organization VDC "Demo-Org-VDC" is deactivated or it is not ready".

- I have tried disabling / Enabling Organization VDC

- Tried upgrading vcloud director databases

- Checked logs found Internal Server Error

- Restarted VCD services

Attached is the screenshot of the error, not found any solution on google. Please suggest.

Regards,

Matt.
