Error on phone and pc: HS:NGRESULT DATA MIGRATION OR PLAYER ID ERROR:314:0

Getting this error when trying to login on both pc and phone.
I have already tried the following:

  • reinstall (on both phone and pc)
  • clearing caches
  • change account password

Is there anything else I can do?

Update: tried switching to other regions, but still unable to start hearthstone: same error is still there
