Route 53 domain transfer out - unable to get auth code

I go to https://us-east-1.console.aws.amazon.com/route53/home#DomainListing:

Unlock my 3 domains. The domains are .com domains. Then I click on the button "Get code" next to the text "Authorization code" I get the following message in a popup

"Sorry, but an unexpected error has occurred while getting your auth code. Please retry again. See system status for more information on current system status."

I have tried several days now. As far as I can see there is nothing under system status. I wasn't planing on buying a support plan to solve this one.
