Android connects, then disconnects upon attempted use

[sengsational]

PC Stack: Windows 7, sshfs-win-manager-setup-v1.2.1.exe, sshfs-win-3.5.20357-x64.msi, winfsp-1.8.20304.msi Android Stack: Moto G5 plus, Android 8.1.0, Banana Studio SSH Server 0.9.2

Used "Add Connection" and connects successfully (no errors). SSH Server on phone shows successful connection.

Problem: When any attempt is made to use the drive letter in Windows Explorer, the message "(the connection) was disconnected due to a connection error" appears.

The following appears in the debug window:
