Error: Kobo server is down when submitting form

Hello, im having an issue when I try submit a form. Shows the following error:

Its happening since 10:30am UTC-3

@Cecilia_nascimento, could you also let us know the server you are using? Does this happen when you are tying to edit a submission?

How can I see what is my server?

Im using server from Brazil, Yes, its happening when I try to edit a submission.
