I guess we can remove the // TODO here?

[rafaelks]

@cardoso Nice one! This PR is removing the fallback compatibility for logins with WebSocket already?

[filipealva]

Looking good! Ready to merge after solving the conflicts 👍

[cardoso]

@rafaelks It wasn't needed. I was just doing it if there was any error with the HTTP login, but it shouldn't happen. It's better to remove the code.

[rafaelks]

@cardoso Got it! Just need to resolve the conflicts then 👍
