How to Verify Your Sending Domain? Having Difficulty

Hello,

I am unable to verify my sending domain in order to add stripe and also to add convertkit. I keep getting an error that says "not a valid host name" or "not a valid IPv6 address" etc.

What am I doing wrong?

I am attaching screenshots below.

I had the same issue – Google gives the code with a period at the end, and Squarespace is rejecting it. Delete the period and try again!
