OK, first, there is an FTP server at that address:
21:32:33 Status: Resolving address of robertoschneider.de
21:32:34 Status: Connecting to 126.96.36.199:21...
21:32:34 Status: Connection established, waiting for welcome message...
21:32:34 Response: 220 FTP Server ready.
This confirms the problem is likely at your side. Do you have any firewalls that could block FileZilla (happens usually following an update). If you want to test an FTP server in the future, just use our http://ftptest.net
testing facility. Note it can't test FTP(E)S and SFTP, so far.
Now a word concerning the network assistant log:
The test is for checking correct client configuration. To pass it you need to read Network Configuration
and set up your client+network for FTP Active mode.
