same problem here!!!
Getting this as well, have tried closing/reopening, logging into web browser. No way to get into game.
Boa noite, estou com problemas para acessar minha conta, coloco em aceitar os novos termos e volta para a página inicial para colocar a senha novamente, já tentei diversas vezes e nada funciona.
Worked for me, thank you!
Funcionou pra mim quando eu limpei meus dados de login, desmarquei a caixa de lembrar dos meus dados e preenchi o login e senha manualmente. Depois disso tive que clicar em aceitar os novos termos algumas vezes e entrou. Espero que vc consiga!
getting the same error
This is how I managed to get into Classic WoW:
I clicked on the “continue without logging in” button to open Bnet, then found WoW in my installation folder and ran “WoWClassic.exe” and managed to get into the game. Also tested with Dragonflight and it works. I don’t see why this wouldn’t work with D4, OW etc. Test it and let me know 
Yep this worked here for me too! Nice work
Guys uninstall battle net and install as new one it worked for me and plus do all command to delete all folders with battle net it worked.
As “retarted” as it may sound, uncheck the “Keep me logged in” box and try again to login.
Something goes wrong with the cached credentials/information. Reinstalling the battlenet client might not always fix this.
Howdy Everyone!
This issue should now be resolved. I’m going to close this thread but if you run into this error again please start a new thread.
