DeepL key is not recognized

Crowdin says “error with key” when I add DeepL key into configuration. We have a paid subscription both in Crowdin and in DeepL (pro plans in both services).

What can be the issue?

@Alessandro_1two you need and API subscription only, an API based

With another one it wouldn’t work as Crowdin (most likely, I suppose at least) uses an API to contact DeepL servers and run the pre translate.
