We've been using Facebook Live Video Events for more than two years to stream successfully (most of the time). We've found that it's more reliable with "Go live automatically at scheduled start time" OFF.

But, for the past six weeks, the prescheduled Event livestream fails, but then facebook.com/live/producer Go Live works fine. (i.e. w/the proper streamkey set, pushing Stream stays yellow and then generates an error.)

Any insights?

The logs don't provide much insight.

It can't be a bandwidth issue, since the "Go Live" works immediately.
