Can't login via cli or Ionic View app


I’ve signed up successfully and created my first app. Now I want to use the cloud services but I can’t login via the ionic client or the Ionic View app.
The client shows this error:

app>ionic login --verbose
[DEBUG] Load global plugin @ionic/cli-plugin-proxy

The Ionic View app says “Invalid credentials”. I’m able to login with these credentials to this forum and the ionic dashboard. I also tried to set up the proxy as described here but didn’t help.

Kind regards
