Hello @aymaneallaoui! Could you please provide the logs or maybe network tab response for the request that is failing? Without these it's hard to say what might be wrong.

I would check the tool and platforms configuration to make sure the URLs are correct. I would also check if both tol and platform are accessible to each other (If one is hosted and the other is running on localhost, the requests will fail, for example).
