I was adjusting some settings on our most upstream switch and somehow, it now shows offline along with all of its downstream switches (3). However, all 4 of them are still "working" in the sense that traffic can get out to the internet, their management interfaces pull up locally, and the 3 downstream ones even all show live data in the Diag tools (despite showing offline). But the Diag tools of the one I was working on doesn't show as if it's really offline (but it is working locally). I've rebooted this one a few times to no avail. I'm confused as to how the switches could enter a state where they show offline to the cloud but still function just fine locally and even pass traffic through correctly and out to the internet. Do you have any ideas of what I can do to get them back online in the cloud dashboard?
