DKIM verified, then magically unverfied!!

Hello

I got an automated email from AWS saying mail was verified (MessageID from AWS is : 0100017956b26d51-9d3b5406-9e49-4c74-9e4c-f0686f6ad00d-000000@email.amazonses.com )

And, on the console, I now see DKIM as "unverified"!

We have not done any changes to the DNS

Can someone please help?

Thanks
