An error is shown when trying to open File Manager for NG webspace in CCP:
Invalid backend configuration. Readable volumes not available.
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 220.127.116.11 PING 18.104.22.168 (22.214.171.124) 56(84) bytes of data. --- 126.96.36.199 ping statistics --- 4 packets transmitted, 0 received, 100% packet loss, time 3001ms
Please fix connectivity issues: webspace should be accessible from File Manager host.
