I had just encountered similar problem this evening. I previously unplugged my ScanSnap Evernote Edition Scanner and put it aside to make some room for other things for three to four months. This evening, I plugged the scanner back and it did not let me scan. I had to re-connect the cable and re-configure the WIFI connection between my laptop (MacBook Pro) and the scanner, but still, I could not access to the ScanSnap Cloud using the ScanSnap Home software. It kept saying "failed to access ScanSnap Cloud". I ended up scanning my documents to my laptop ScanSnap folder and importing them manually into the Evernote. Then I saw this post. After reading all your suggestions (Thanks, everyone!), I installed the mobile version of ScanSnap onto my iPad, signed in, took a picture as a test, and the photo was uploaded to my linked Evernote. Then I went back to my laptop to try the ScanSnap cloud. This time, it asked me to connect the scanner with the cable. After I connected the scanner and the laptop with the cable, I was able to connect to the ScanSnap Cloud. Not sure it was the server problem on the ScanSnap side or something on my side, but it seems working fine now (after four hours of struggling).
