This will happen if your connection is interrupted for any reason. We value connection integrity, so any little interruption in network connection to our Silo servers is seen as a threat. If you change internet connection or connect/disconnect to a VPN, you will see this error window. If you believe this is happening without a network connection change occurring, please contact firstname.lastname@example.org
Please contact Support if you have additional questions, or require further information about Silo.
