It doesn't say webapp failing back to HTTP, but looks like Guacamole is using
HTTP tunnel instead of WebSocket, not sure if this is default.
Note " Using HTTP tunnel (not WebSocket). Performance may be sub-optimal."
occur when initiating file transfer from remote system.
Another question is, does ssh host verification play any role in transferring
files ?.
I have restarted nginx, guacad and tomcat9, still no joy.
nginx configuration support websocket.

Do you see any messages in the Guacamole (not guacd) logs noting that
the webapp is falling back to using HTTP as WebSocket could not be used?
There may be something interfering with use of WebSocket. If this
happens, the HTTP tunnel will kick in and alternate between a pair of
HTTP connections to achieve the same kind of streaming, and that will
prevent downloading files due to browser throttling of HTTP requests:
