Signing in and signing up not working

I am pulling my hair out trying to use Kami from google drive.

When I click “sign in with google” it thinks for a moment then returns to the same login page.

When I click “login or sign up” it prompts me to fill in the email and password fields. Once I do, it tells me “Unable to connect to the server. Please check your connection and try again.”

Next, I tried forgotten password (since other websites this sends an email that prompts sign up), but NOTHING happens, not even anything in spam.

I have restarted chrome, restarted my computer, searched the help centre and I can’t find anything to help. I am very close to giving up altogether, so some help would be appreciated.
