Error 053 is ok since that asset is not available. But Error 056 should not happen, however I can also confirm the problem.
The historical data of that contract is not available. We found other contracts where it did not work either. We're currently checking with IB API support what the problem might be. Please stay tuned for the next attempts.
Thanks for checking, but why should that asset not be available? It is the latest expired FDAX exp. date 17/03/17 , at 7:13 UTC, which is 9:13 CET, so during normal session hours?
