Difficulties with Deepl

Hi everyone

Can somebody please help me making Deepl Connector work ?

I've put one sentence to be translated in column A
The formula in column B is the following :
=Connector("Deepl.Translate";Feuil2!A1;"FR";"EN";"Result,DetectedLanguage";VRAI)

But i get a error

We've had issues with the DeepL API in the past, somewhat unreliable.

Is it possible to borrow your API key to debug? If so, send it to me via PM or email victor@seotoolsforexcel.com
