Two possible solutions:

1: Restart the server end, terminate all local client instances, and try
your command again.

2: See if it works with two client instances, one to set up the local
redirection, one to set up the remote redirection.

This is just a guess on my part, but I think this would work around a
bug/feature involving the data structures used to track the endpoints of
such tunnels. Googling for the exact error message (minus the port
number) will lead you to more info.
