My webspace hoster (webspace4all.de) supports only TLS 1.2 for security reasons. (I can't change this and I understand this.)
In the log of owncloud I find nothing. In the log of my webspace I find: "GET /ocs/v2.php/apps/notifications/api/v1/notifications?format=json HTTP/1.0" with status 200.
I don't know whether the HTTP/1.0 is the problem.
But as I mentiod at first the solution is to enable TLS1.1 and 1.2 for Android 4.1, 4.4 and 5.0 inside of the app. (It is by default disabled) "To enable TLS 1.1 and 1.2 you need to create a custom SSLSocketFactory that is going to proxy all calls to a default SSLSocketFactory implementation." This solution is described here https://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/.
Due to my same hints zc2 from GhostCommander did this and the result was perfect. Thank you very much to them. https://sourceforge.net/p/ghostcommander/bugs/43/
If you can realize the solution of https://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/ for Keepass2Android this would also be great. (I can't it. I'm not a software engineer)
