Sounds like 1. BS Cloud doesn't like your device or 2. You have a VPN on the toshiba that is filtering or 3. Your local wifi/lan firewall is filtering your Toshiba (and not phoen or pc) or 4. you have some sort of firewall on the Toshiba or 5. the app manager is blocking the app from connecting or 6. the upgrade went wonky with some left over code. I vote #6 and would suggest removing the app and installing it again.
