For me, it used to be like you describe several versions ago of the Gateway. No data farm problems [but only a blocking re-login prompt, that after a lot of insistence (even here on ET, as you can see from old posts) they finally removed.] Probably they re-introduced issues in more recent versions, as I can see that the post on "groups" is from Jan 2018 . Particularly, I am running version Build 972.1r, Feb 12, 2019 11:03:55 AM. The problem to me appears at least once a day, and restarting the Gateway is needed, or else there is no programmatic way to awake the "usfuture" data farm (the Gateway remains normally connected, only the data stops and a yellow line appears on the interface). And I have heard the same problem described here from many people.
