{soundcloud] App fails to login (first after install) on e os 1.0 with microg

I have e os 1.0 on my phone, which uses microg instead of Google Services. After installation of the Soundcloud app, I can not login to my soundcloud account. The error message tells me, login failed and I should go to registration.

I verified of course that login and password are correct. I can sign in the website.

How could I get insight on this error? Is this a Play store/Google Apps issue?

Best, YeOldHinnerk
