The session negotiation failed

[koolstoffen]

Hello! I tried to set several pc’s with NoMachine server free to control them. On one everything is good, but another one gets an error (after enter login and pass): The session negotiation failed

One difference between them – second has shared internet connection to the second net card (local net)

Connection log ends with: NX> 595 Server could not establish communication with local node.

Session starts with: 5700 5228 16:47:54 299.377 Socket: ERROR! Failed to duplicate FD#0. Error is 6 ‘Specified event object handle is invalid’.

Error: Failed to duplicate FD#0. Error is 0 ‘No error’.

92 16:47:54 013.361 Main: Exception handling library not loaded.

Then have several warnings:

492 2236 16:47:54 137.368 MdnsdListThread: WARNING! Could not open directory ‘C:/Users/Администратор/.nx\cache’.

…and ends with:

Can you describe in detail exactly how you share the internet connection for the wrongly working machine?

Is this Access Point connected to the same router as the first machine? Maybe you could share internet from first machine?

I have on first machine 2 ethernet cards, 1 in internet, second in local lan only. I share internet from 1 to 2 through Windows settings

Can you send server (%PROGRAMDATA%/NoMachine/var/log) and client logs (%USERPROFILE%\.nx) from server side to forum[at]nomachine[dot]com? Instructions about collecting logs you can find here: https://www.nomachine.com/DT10O00163
