Connecting a Domain: Connection Failed

Hello,

I have followed all the steps to have the Domain Connection complete. DNS and A records were successfully pasted into the Domain Provider's Control Panel. After 72 hours, the following message appeared:

Connection Failed 

We could't verify domain ownership with Other.

VIEW DNS SETTINGS

See attached.

I clicked on the Red Exclamation mark in the Connection Failed message. It suggested using a TXT Record to verify the Domain. However, my provider does not have TXT as an option. I thought I would disconnect the Domain Connection attempt, and try again. Still no result. Please note. I have had this exact Domain working with SquareSpace in the past, and the current Provider is the only Provider who has owned the Domain since inception. It is a .com.au Domain, so Transferring to SquareSpace is not an option with SquareSpace.

Please help.

Thank you.
