Resolution
The problem could be caused by network problems, e.g. it is impossible to connect from File Manager host to NG webserver. To verify it, try to connect to port 21 from File manager host:
# ftp ftp.d1234567-1234.provider.tld
Timeout..
Try to ping the host with webspace:
[root@fm01 ~]# ping 5.4.3.2
