the shutdown of the legacy node was announced 18months ago... the date was set for January already.
You seem to not have read any of the countless notifications and posts and now seem to not have followed what it says in the error message.

didnt got any of these countless notifications. I just imported it to zeus time ago. anyway. my fault.
seems you did not even login to the account dashboard now and follow the instructions there, what would you expect from us?
seems you are also fully aware that you use an external service - which now was announced to be shut down.
since 18+ months we fully work on the self-sovereign lightning wallet and told people to migrate.
