it won't let me add domain name
Digital Ocean doesn't have any restriction on domain name, right? I redirected my domain name from Bluehost to digital ocean 4 hours ago. When i tried to add domain to my droplet, it always gave this error message saying: Name only valid hostname characters are allowed.(a-z, A-Z, 0-9, ., _and - ) Or a single record of "@". My domain name is usorgames.net. I don't think it is abnormal. Can someone help me here? Thanks.
