Inaccessible to the Network (Connecting to the ScanSnap Cloud Server Failed).

Causes and solutions for when the device is inaccessible to the network (connecting to the ScanSnap Cloud server failed) during the ScanSnap Cloud application setup are explained below.
Cause

The issue may be caused by the following:

  • A static IP address is set to the ScanSnap.

  • Multiple routers are used.

  • The wireless access point is set not to use the 2.4 GHz SSID.

  • The signal from the wireless access point is difficult to receive.

  • A DNS is not set for the wireless access point.

  • Connection to the Internet is established via a proxy server.

  • A public wireless access point is used.

  • The ScanSnap or the wireless access point is turned off.

Solution

Check the following items, and then try again:

  • When a static IP address is set to the ScanSnap

    For the ScanSnap Cloud service, a static IP address cannot be used.

    Start the ScanSnap Wireless Setup Tool and change the settings to obtain an IP address automatically.

    For details about how to start the ScanSnap Wireless Setup Tool, refer to Unsure How to Start the ScanSnap Wireless Setup Tool..

  • When multiple routers are used

    Establishing a connection to the ScanSnap Cloud server may fail.

    Disable the router function on the wireless router and check whether the connection can be established.

  • When the wireless access point is set not to use a 2.4 GHz SSID

    If there are two types of SSID (2.4 GHz and 5 GHz), the 2.4 GHz SSID needs to be used.

    Change the settings of the wireless access point to use the 2.4 GHz SSID.

  • When the signal from the wireless access point is difficult to receive

    Place the wireless access point and the ScanSnap closer to each other.

  • When a DNS is not set for the wireless access point

    The ScanSnap does not have a function for setting a DNS. Therefore, if a DNS is not set for the wireless access point, connection to the ScanSnap Cloud server cannot be established.

    Set a DNS for the wireless access point.

  • When connection to the Internet is established via a proxy server

    Configure the settings of the proxy server in the setup procedure.

  • When a public wireless access point is used

    The ScanSnap Cloud service cannot be used via a public wireless access point.

    Connect to a network other than a public wireless access point.

  • When the ScanSnap or the wireless access point is turned off

    Turn the power on.
