Cant play on EU NGRESULT DB ERROR:303:0

Hey,
Haven’t been playing hs for 5 years. Came back and while logging on EU server wich is my main and had all the stuff there im getting NGRESULT DB ERROR:303:0, while on other servers works normally. The support gave me 7 steps wich didnt help, and at the end they “refreshed” acc but this didnt help either.

Any ideas what to do ?

I have the same issue as described by OP with 3 different devices (DB ERROR 303 on all of them):

  • iPad Pro 11" 2021 (latest updates installed)
  • iPhone 13 (latest updates installed)
  • Windows 10 PC

I followed the steps (reinstall, cache, try different platforms and devices etc.) and nothing helped. Couldn’t even create a ticket since they don’t offer mobile support and I don’t intend on playing it on PC.

Would be glad to receive help
