subscription-manager registration error

I registered my server on RH site two weeks ago and everything was working fine, Developer asked me to delete the VM and create a new one with same name and same IP address.
I deleted the VM and also deleted from the RH registration site. I created a new one with different IP address but when i try to subscription-manager register I am getting error message.

I am not sure if RH website will take some time to register the same name server, Can you please tell me what to do or I ahve to wait some time
