I keep getting returned to the Title Screen with an error. Errors are (ordered by frequency):
  1. 90006
  2. 90002
  3. 90007

This began last night (20180203), while I was in a raid (o7s)

This is happening about every 30-45 minutes

I read through a couple other threads reporting similar things (below). One thread suggested a VPN. I installed and configured WTFast. Didn't help

Any ideas?
