Just for reference, the above cause as mentioned in today's update is incorrect.
I'm getting this error on a wired Fiber to the home connection of 300/300 and a wired ethernet connection to switch and router.
This has nothing to do with wi-fi or unstable connection from our side.
This is at the data center side. And quality of home connection doesn't seem to matter.
