I have setup this option before on the DX4000 without this issue occuring.
I’m trying to setup remote access, click setup under Domain name, this takes me to the getting started page.
click next takes me to the “Do you own a domain name?”
If anything is pressed the “Next” button is greyed out and then a message is displayed
“An error occurred while setting up your domain name”
I have also noticed the above error message can occur at any point in the setup process, it seems to take around 20 seconds before it is displayed
