Package: unknown
Version: 4.1.2.2


Howdy,

	When I connect from Mac client to ubuntu server, I get a “connection timeout” 30 seconds after “connection start.”  Other people can connect to my server.

Error message is:
Loop: WARNING! Overriding auxiliary X11 port with new value '1'.

On the server, in /var/log/messages, I get what appears to be a success report:

I have a tcpdump (is in an ssh tunnel, to a little vague) which shows client sending dup packet not quite, but almost 30 seconds into session attempt.

Try to upgrade nxagent on the server to 3.5.99.26 and see it this
helps. See https://github.com/ArcticaProject/nx-libs/blob/3.6.x/README.md
for instructions where to find a current binary package.

Subject: Mac client: connection timeout 30 seconds after session start

Date: Thu, 28 Oct 2021 22:22:47 +0200

Tried upgrading to 3.5.99.26, but this changes nothing.  MacOS client is 
4.1.2.2.  Server is Ubuntu 20.04.  After building nxagent I get

nxagent -version
NXAGENT - Version 3.5.99.26

The result stays the same: server started successfully, followed by a
timeout after 30 sec.  Connection using an Ubuntu 20.04 x2go client
works fine.

	Thanks --- Jan

Ich habe Ihnen diese Nachricht geschickt, weil ich Ihnen im Zusammenhang
mit dem Tod des Ingenieurs Marcel schreibe, der etwas Geld auf der Bank
hinterlassen hat. Nachdem ich erfolglos versucht hatte, seine Verwandten zu
finden, beschloss ich, Sie zu kontaktieren. Bitte lassen Sie mich wissen,
ob Sie diesen Mann kennen.
