1. A system comprising:
a router device; and
a first adapter device in communication with the router device, wherein a first encrypted connection exists between the first adapter device and a remote device, and wherein the first adapter device is enabled to:
determine that the first encrypted connection between the first adapter device and the remote device is offline based on an irregularity in a packet header or a packet tail of a packet received by the first adapter device; and
output a message to the router device that the first encrypted connection is offline,
wherein the router device communicates with the remote device via a second adapter device and a second encrypted connection configured to bypass the first adapter device.
