No Android login to 10.0.2

Hello,
i tried to install owncloud 10.0.2 for 30 times now.
versions up to 9.x work totally fine
i tested installations on debian 8, using apache2, php5 or php7, using mysql or mariadb
everything's fine and no problems.

after installing 10.0.2 (i tried fresh installationds and updates) webui works fine. windowsclient works fine and synch works perfect BUT
i cant login with android devices.
i alwyas get: 401 No 'Authorization: Basic' header found. Either the client didn't send one, or the server is misconfigured, No 'Authorization: Basic' header found. Either the client didn't send one, or the server is misconfigured

is there any new dependency for the server to be fulfilled or any php-files to edit to get rid of this error ?

i aslo searched the wed for that issue, but i did not find any site with a usefull WORKING solution for this problem
i spent days and ancounted hours in that prob withou getting it to work.
id be thankfull for a working hint/solution

regards
wsxws

PS: Solved, i deleted owncloud and installed nextcloud 12. this works perfect.
