Mac Client accessing Linux Server : No Route to Host

[kcat]

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

[kcat]

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

NoMachine 8.14 has been released. Please update your Mac installations via automatic updates or using the NoMachine packages which you can download from our website, and follow the instructions here:

I’m still experiencing this problem, launching from the terminal does not help

 

[Britgirl]

emilianoheyns, can you confirm that you are still experiencing this issue on Sequoia after updating to NoMachine 8.14 and after following the instructions in the article I linked earlier?

https://kb.nomachine.com/AR09V01251

[emilianoheyns]

Yes, confirmed. Strangely enough, after installing [removed] as a service on the Linux machine, NoMachine now does work.
