[X2Go-User] x2go client on fedora 40 rc2

I'm trying x2goclient from fedora 40 rc2 client to fedora 39 server. Connection fails at startup "the remote proxy closed the connection during negotiation" There should not be any authentication problem as I can ssh without password. The client then segfaults.
