AD Connector inoperable state - Unable to delete

Hello, I have been experimenting with Workspaces and created an AD connector and an EC2 instance as a Domain controller. The EC2 instance got deleted by mistake and this moved the AD connector to the "Inoperable" state. I cannot delete the AD connector now and when I try, it gives the message "On-premises issue(s) detected by instance 10.101.1.138: Unable to reach DNS port (TCP 53) of on-premises server 10.101.0.37. On-premises issue(s) detected by instance 10.101.2.164: Unable to reach DNS port (TCP 53) of on-premises server 10.101.0.37. How can I delete this AD connector? This was all created via terraform and I am now stuck. Please advise.
