Lightning server could not reach the network shared folder you have input previously. It could be a wrong IP address or wrong path of the shared folder.
- Please make sure the path you have input is correct.
- Please make sure the path you have input is complete. For example, if the shared folder address is '192.168.1.2/music', you can not input '192.168.1.2' only. A full path is always required.
- Please make sure the 'PING' function (ICMP) is enabled in your network on the machine which has the shared folder as Lightning Server will try to ping the machine to verify if it is alive first.
