Ok what do you mean by Verified clock date and time? Define verify. My clock has always been correct to the right minute, which I manually did, my computer doesn't let me sync with a timezone to be 100% exactly correct, so I have now manually synced the time correctly to the second, when I have my computer clock up next to the one I have found on the link you gave me, it looks exactly the same. But the same problem persists when trying to log into the cloud, are you trying to say my computer clock has to be correct to the right millisecond/nanosecond or something?
I do not work for Adobe support, so only had an IDEA based on your error message
