My device does find AirServer Connect as a wireless mirroring device, but connection fails each time.

This mostly has to do with how the Miracast Connection is made between sending and receiving device. When a miracast connection is made a handshake between both is done, requiring a return signal from AirServer Connect to sending device. The way Miracast works is that after the initial handshake over port 7250, the receiver (AirServer Connect) connects back to the client typically over TCP port 7236. If the client firewall or the network infrastructure prohibits this, connection will fail. A way to check this is to (temporarily) disable all firewalls. To do this, go to Setting and select Windows Security. Here you can disable firewalls, or change their setting to allow AirServer Connect to communicate back to the laptop.
