Since 15:20 all calls for the order endpoint will lead to a time out.
Therefore you are not able to do a GET call on open orders or confirm order Shipments.
We will update this message, we think it is fixed before 16:30
Our apologies for the inconvenience.
Update 16:30: We are still working on a fix for this issue, next update is at 16:45
Since 16:40 this issue is resolved.
