Getting "The session negotiation failed. Error: Last operation failed"

[ashutosh]

I got the error when tried to connect to ubuntu amazon server from ubuntu client machine.  I downloaded the package nomachine_enterprise_server_evaluation_amd64.deb package and  nomachine_enterprise_server_evaluation_i386.deb.

After entering all details I got error after I entered the username and there was option to create virtual desktop. When i clicked on create virtual desktop option. It throws me this error. “The session negotiation failed.Error: Last operation failed”.  When I tested the server status then I found that nxnode was disabled. When I tried to start nxnode separately it shows me no subscription error. When searched for this error found that this could be a license issue so checked license files, license files was node.lic.old and server.lic.old instead of node.lic and server.lic. I had attached the error logs files I got from NoMachine.

I installed NoMachine free edition too on the amazon server but it shows error that ssh is disabled on the server.

Hi, please avoid posting long excerpts of logs and use the attachment tool instead 🙂

From what you’ve written, your installation seems broken, license files were removed and permissions changed.
Please uninstall packages, remove /usr/NX directory and perform a clean installation.

The NoMachine Free package doesn’t provide SSH support. SSH support is available in the NoMachine for the Enterprise range.
