Can't add domain

[d.wgp89]

I have tried adding an addon domain (danoushm.com). It does not show up in the addon domains section in cPanel and when I try to add it, an error message appears saying the domain has already been configured. There is a folder for my domain in the File Manager.

Also, when I try to change my main domain to http://danoushm.com I get the following error: C085843B

Any suggestions?
Thank you

Hello,

Please try now. Looked like a previous, failed, attempt had left entries behind for the domain. I have cleared that out now.

Hi thanks for your reply. I now get this error message when trying to create an addon domain:

There was a problem creating the addondomain. Show Details

Error from park wrapper: Using nameservers with the following IPs: 99.198.122.2,173.236.27.195

EDIT* After trying to add the domain a second time I get this error:

There was a problem creating the addondomain. Show Details

Error from park wrapper: danoushm.com is already configured.
