Hell @fabrice,

Welcome to the Prismic Forum.

I see the same issue happened with another user too. Please check this thread, It can be helpful for you:

Unauthorized when running Slice Machine, trying to add my own slices to my CMS

Hello all, Getting up to speed with Prismic and Slice machine which looks awesome. I'm now exploring building my own slices. I'm having a few teething issues launching Slice Machine. When running prismic sm --develop I receive the following error [slices API]: Unauthorized Story block is running in another terminal window. I am signed into Prismic CLI and have tried to re-enter my details with no joy (same error as above) Any tips to where I may be going wrong? Thanks Jake

And also we published a troubleshoot guide, here:
