Stripe : register sellers

Hello,

I am trying to register a user as a seller but I always get the error below :
(translation : Sorry, due to a technical problem we cannot register sellers at this time. Please try later)

I tried Stripe plugin and Stripe.js 2 and both return the same error, I’m not sure if this error comes from the Stripe plugin or my Stripe configuration. Has anyone ever encountered the same problem and can help ? Thank you.
