You were disconnected from Blizzard services

Getting - “You were disconnected from Blizzard services”

  • power cycled router
  • did ipconfig release,renew,flushdns
  • SC2 works fine but HOTS doesn’t
  • deleted c/programdata Blizzard and battlenet folder but issue still persists

UPDATE - After giving up for an hour, it randomly started work -_-.
UPDATE Dec11 -
Problem is back again.

Never had this problem before but it randomly resolved itself after an hour or so last time. After it sorted itself out, I had been able to launch and play games as expected numerous times till now.

Are there some some maintenance or server issues for NA servers?
