    I have a NoMachine Cloud Server running on Windows. I also have NoMachine Cloud Server running on a Mac. I can connect to the Mac from the Windows machine using NoMachine. I can run the webplayer on the Windows machine and see the MAC. When I connect, I see the Mac computer but when trying to connect I receive the message, OOPS the connection with the server was shut down.

    I have edited the config.cfg to configure the sectionsession and I have added the client certificate as per the Cloud Server Installation and configuration document.

    We are using ConnectionMethod NX

    Any Suggestions?

    Thank you, Peter

    Hello Peter,

    We will need debug NoMachine Cloud server logs from Windows machine to investigate further. Please follow the instructions here:

    https://www.nomachine.com/DT07M00098#1

    especially point 1.3:


    1.3. If you have a Cloud Server installed and the problem affects sessions by the web:
    Edit the /usr/NX/etc/cloud.cfg file. Uncomment and set the following:

    SessionLogLevel 7

    Hello Peter,

    unfortunately not all logs were sent, the most important ones were: nxerror.log and nxserver.log, which were missing.

    However, looks like certificate of MAC machine was not added correctly on Windows server.
    Please try to add again certificate as described in article:

    https://www.nomachine.com/AR07K00679

    If certificate was added incorrectly in nxerror.log you will see logs similar to those below:


    1812 10092 16:51:35 674.464 Encryptor/Encryptable: ERROR! Failed to authorize the server certificate.
    Error: Failed to authorize the server certificate.
    1812 10092 16:51:35 675.465 Channel/Channel: WARNING! Runnable DaemonReader failed for FD#768.
    1812 10092 16:51:35 675.465 Channel/Channel: WARNING! Error is 13, ‘Permission denied’.

    If still you cannot connect to MAC machine using Web Player, pleease send to us logs, and please be sure that all logs are added – especially nxerror.log and nxserver.log.
    also please send to us client.crt file from Windows machine


    %PROGRAMDATA%/NoMachine/nxhtd/.nx/config/client.crt

    and certificate taken from Mac OS, which were added to client.crt on Windows:


    Konsole output
    /Applications/NoMachine.app/Contents/Frameworks/etc/keys/host/nx_host_rsa_key.crt

    Hello Peter,

    as we checked the logs and the client.crt looks like certificate was wrongly added in client.crt.


    4276 3592 16:02:13 565.711 Encryptor/Encryptable: ERROR! Failed to authorize the server certificate.
    Error: Failed to authorize the server certificate.

    Please take a look at file client.crt:


    Host:172.16.73.203—–BEGIN CERTIFICATE—–

    the HostName and certificate should be splited into 2 separated lines, so it should looks like:


    Host:172.16.73.203
    —–BEGIN CERTIFICATE—–

    Please correct client.crt file as shown above, and now it should work.
