Hi Mounir, Two things to verify: one is that you are using a timestamp that is within about 5 minutes of our system clocks. We return the current time in a Date HTTP header with every request. Second, verify that you've never used the nonce you are creating for each request -- this is across all requests your API key makes.
Are there different machines you run your code on when it works versus when it does not?
