# Issue details

### Duplicate?
no

### Actual behaviour
- It's not possible to login with the wizard
- same problem if i define the client-id und the client-keys manually
- in Webbrowser login is ok

### Expected behaviour
Sucessfull login

# Steps to reproduce the issue
1. Start App
2. Type login-data
3. Get Error-Message: "Verbindungstest fehlgeschlagen: Autorisierungbezogenes Problem: Diese werden meist durch HTTP-Umleitungen verursacht". I think this is error ConnectionTestResult.AUTH_PROBLEM: https://github.com/wallabag/android-app/blob/0a9fbe987619656c792c694e474e0acde7810dae/app/src/main/java/fr/gaulupeau/apps/Poche/network/WallabagWebService.java#L145

I think there is a problem with the cookies.
