Domain Cloaking Error

We're sorry, we had a problem with our web panel when you set up cloaking for your domain 3950.net!
Please go to the DreamHost Web Panel's Domains > Manage Domains area and click the [Edit] link next to 3950.net to re-configure cloaking.

Error: no domain www.3950.net or 3950.net; if you recently set this up, please wait up to one hour.
