Can't login to Lg Account

So today I bought an a2 oled tv and my problem is that i cannot sign in to an lg account. I want to download Hbo Max but an account is necessary to download it (idk why if i can download other apps). Instead of the login page i got an error maeedage that says "the lg service country information could not be retrieved from the server". I tried changing my service country to a lots of countries but nothing. I tried different wifi networks and ethernet and hotspot from my mobile but nothing happens. I also tried accepting all terms of service and still cant login. What should i do/try? Any help would be appreciated.
