google translate not used for language pair

Hi all,

in a project I received from a customer, I'm trying to add google translate. I get a message that google translate „will not be used for the following language pairs:" - and exactly the language pair for this particular project is indicated.

Then, I see google translate is there, checked, but it does not work, no segments populated.

What can the reason be?

Kind regards,

Clemens
