When I try to add my domain name in my DO control panel I keep getting an “invalid hostname” error. My domain name ends in “.io” - why is this invalid?

The .io domain extension shouldn’t be invalid by any means. I own a few domains with this extension and they’re setup + working on DigitalOcean as I write this post.

I did just test to see if an error would pop up when adding another. I chose a domain that isn’t actually setup,, and it was added without any issues.

If you’re unable to add a domain through the control panel, I would recommend submitting a support ticket and let them know of the issue so they can see if there’s details that they can provide you with.
