NX key authentication – cannot make it work

[maximn]

hello, I am using last version 6.5.6 (free) on Windows. i followed this guide to enable nx key based authentication https://www.nomachine.com/AR02L00785

For some reason it is not working – all i have, just a message “authentication error” on client and “Public key not recognized” in server logs

here are my files:

1. c:\Users\nx\.nx\config\authorized.crt

ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCf6vK6aZoFlYMJUiMI68hyraC4XzF9pA8aVLVOEFGaYnmPK2cnxDd1cwLkVkzdLSzR3GK0vLgxFgaUrU8NYQny5GDhtz4wgEDexgEksm/bZLJKNX5CCqrNgnYVAG5X1Vg0T+M6+YechHIOXIFggcDcMvcVBcuP2fc0omsA1u/LJUoX+F6vqIzn2wwUh0Oe5oSbJ6qnXKpZMkmVzNmsK9fdOjBwPLUjw3yUcZiM9fNcIaRuUE0whnUcF/Kes5QaRtg6pqtf224yLJveHzUmZj06ZqTFXtfxdgO3MHV5vh0V2yK0SBHYQakRSWHMxRQRyfd0CyVeROZyoFkfJX3CHeSR

okay, have it working after couple hours

1. if passphrase in the key file is empty, passphrase and username are never asked

2. authorized.crt must be not in “c:\users\nx\.nx\config”, but in the above users folder – “c:\users\username\.nx\config”

Hello maximn,

Did you generate a new pair of keys? I ask because we have a Trouble Report for which the temporary workaround is to generate new keys

ssh-keygen -p -m PEM -f

Here is the TR: https://www.nomachine.com/TR02Q09140

Btw, we noticed that you are trying to connect as user account named “nx”. We don’t recommend it, because the nx account is needed to setup the initial stage of the client-server connection. Please use local account profiles.
