    Hi all,

    My mac is on the local network sitting next to my linux box.  I used to be able to connect but lately I am seeing issue.  The error says something to the like of cannot find route to host.  (However, I can successfully ssh into it).

    Upon openning the connection log, it seems to say that the client cannont open a TCP connection.   (protocol ‘TCP’ failed’)

    mac is running Sequoia 15.1 ; Linux is running on Ubuntu.

    Help appreciated.

    version 8.13.1.

    Hi kcat, this is a known issue with the latest update of macOS. We are currently working on a fix which will be released next week. In the meantime, you can read more about the problem here: https://kb.nomachine.com/TR09V11212.

    Possible workarounds for macOS 15/Sequoia:

    1) try re-logging in (logout-login on local), then connect again via NoMachine.

    2) or launch the NoMachine client from a terminal:

    /Applications/NoMachine.app/Contents/MacOS/nxplayer

    I have exact the same problem trying to connect to a Windows PC from my Mac. I’ve used NoMachine for at least 6 months and it has always worked. from Terminal I get:  nc -v 172.17.0.130 4000

    Connection to 172.17.0.130 port 4000 [tcp/terabase] succeeded!

    I have upgraded MacOS to Sequoia 15.0 since I last used NoMachine. I’ve looked in firewall settings but I cannot see that I need to change anything.

    Launching from Terminal works????

    Thanks

    Launch the nxplayer & from the MacOS terminal seems to work actually…
