We did not get any specific errors in the log file. But the thing is that if the request is not fulfilled within 5seconds, we cancel it. Until now, this limit was completely sufficient, so even if some requests did not pass first time, they passed second or third time.
Now it seems that this 5seconds limit is not enough for Shopify API to fulfill our requests. At least with the orders. One request asks for batch of 250 orders to return. We are already trying to increase limit on our side, but it would help to understand what changed on Shopify end. Did you change something? Is it performance issue or something else?
