Trouble hooking up new GoDaddy domain name to current one

Hi all!

Sorry if I am getting my terminology a little messed up (all the IT stuff has always been a headache to me :blush: )

Currently, this is my website, I believe I am hosting it through Webflow. Anyway, I purchased a new domain name (through GoDaddy) and wanted to connect it to my current one. When I tried doing so on GoDaddy website (which seemed like it would be easy), but after the network kept “thinking” it eventually said it failed.

Does anyone know if there is an easy way to fix this? Or should I contact GoDaddy or Webflow for this?
