First connection problem

[azizitom]

Hello. First run, WiFi is connecting ok, but when i fill in all starting data i always have error "login failed: synology returns error 400".

In log file i have:
[INFO][SettingsActivity] Getting address : ********:5000 https:false
[INFO][SettingsActivity] Got maxVersions: SYNO.API.Auth=6, SYNO.FileStation.CheckPermission=3
[ERROR][SettingsActivity] Problem during Login: 400

Synology user is ok (normal login to synology from https).
I check login name, password and port. Tray different folders, https but no luck.
I use synology rs812+ and sony a6300 (fw 2.0.1). Everything is in the same network.

Any idea?
