Seems like this issue may have been around nearly forever, but I guess
something changed at some point in the x2go or libssh logging setup that
allowed the ssh errors to get printed.  Basically, x2goclient loops forever
doing (among other things):

        addReverseTunnelConnections();
        checkReverseTunnelConnections();


checkReverseTunnelConnections() calls ssh_channel_accept_forward() which sets
an error if no channel request exists.

Now normally this doesn't get logged because x2goclient sets the libssh log
level to LOG_SSH_NOLOG (quite likely for this very reason).  However, I'm setting:

   LogLevel ERROR

in my ~/.ssh/config file - which has the effect of setting the libssh log
level to 1 and so the errors are printed.

Now, it does seem incredibly inefficient for x2goclient to repeatedly call
ssh_channel_accept_forward() if there are no forwarded connections to accept.
Is there any other way to do what is needed here?

If you just want to get it working, try downgrading QT.

I don't think this message has anything to do with Qt.  X2Go is working fine,
it's just spewing these messages.

qt5-qtbase-5.15.3-1.el8.x86_64

Yes.  This may be an inherent limitation with libssh though.  I've posted a
question there:

https://archive.libssh.org/libssh/2023-04/0000002.html

(BTW - it's not just a few messages - about 1.5k lines / sec on my machine.
