Kindly help on this, I've also reported this issue.
Please check if your system time is correct. I ran into similar issue when my desktop computer motherboard battery died; which created issue with time sync.
We saw this at the same time as well, however, it looks like it was an AWS issue and is now resolved
Thank you for bringing this to our attention, @Jimballoon.
