Unfortunately, you are rather vague about what program you are running and where you are running it, so I can only guess, but there are two recent changes which might be the cause of your problems. 1. If the program is running on a remote host and you are trying to connect over TCP (rather than using ssh tunnelling, the recommended way to do that) you will now need to start the server with the option '-listen tcp'. 2. If you are running the program locally and explicitly setting the DISPLAY variable yourself, you should be setting it to ":0.0" not "localhost:0.0" or "127.0.0.1:0.0" or "::1:0.0" (to avoid trying to use a TCP connection) [1] https://cygwin.com/ml/cygwin-xfree-announce/2015-02/msg00026.html [2] http://x.cygwin.com/docs/ug/using-remote-apps.html#using-remote-apps-telnet [3] http://x.cygwin.com/docs/faq/cygwin-x-faq.html#q-remote-clients-cant-connect [4] https://cygwin.com/ml/cygwin-xfree/2015-02/msg00051.html -- Jon TURNEY Volunteer Cygwin/X X Server maintainer -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
