When downloading historic data for certain futures contracts I'm receiving a 200 status code immediately but the message is empty. This only seems to be happening for the 3rd from front month of the futures contract. The product is LS Gas Oil TAS, the date is 17/12/19 (uk date format) and the RIC is LGOTH0. Another example is the same product on the 02/01/20 with the RIC of LGOTJ0. This is also happening for the LS Gas Oil Singapore product, an example being 01/04/20 with the RIC of LGOmmN0.
Any help would be great,
Thanks!
