Do you mean the cloudron.io login or your Cloudron's dashboard?
Ok so my.cloudron.io is actually our Cloudron company Cloudron. You would not have an account on that.
So either you have to use your owns Cloudron domain: my.example.com or if you mean our accounting portal, which is at https://www.cloudron.io/console.html#/login
This got solved via support ticket.
