Error code. 2-5 Error Info 0-5  

Hi @ericgili,
Did you notice any error notification on your primary machine upon connection attempt?
For further analysis, could you please run dxdiag.exe on your primary machine, click "Save All Information", save the output file (dxdiag.txt) then attach it on your next reply.

PS: Attach option should be visible below the text editor after your second post.

Hi @spacedesk Lea,

No, the only thing could be that on the status says "ON (idle)"

Hi @ericgili,

Thanks for sending your dxdiag.
It shows that you have a splashtop driver on your machine.
Please remove/uninstall splashtop before using spacedesk.
For more info, please check Incompatible Display Hook Driver Detected chapter in our user manual https://spacedesk.net/user-manual/##incompatible-driver.

Hi @vov4ik,

Thanks for sending your dxdiag.
Did you notice any error notification on your primary machine upon connection attempt?
Did you also get "Connected time: 00:00:01" below the error code?
What is your secondary machine (Android/iOS/Windows)?

splashtop driver

sorry but I don't understand what is "splashtop driver" and don't know what to look for.

my secondary machine's OS is Windows 10.

yes, there was  "Connected time: 00:00:01" after error massege 

and this error message (in attached file) was on secondary machine.

Hi @vov4ik,
splashtop driver was found on @ericgili's machine based on his dxdiag info.
While on your dxdiag, no splashtop so you don't have to look for it.

In the meantime, we would like you to send us debug logs on this issue.
Please download the spacedesk diagnostic script here, then extract it.
Inside you will find spacedeskDiagnosticTool.cmd, just right-click it then run as administrator.
This script will start a debug view app to capture spacedesk debug traces.
On step 5 it will prompt you to reproduce the issue (by connecting the viewer app - then will disconnect with error code), make sure to do this before pressing any key to continue.
After the script is done, a folder will be created on the same folder as the script file which contains various log files that we need for analysis.
Please right-click it -> Send to -> Compressed (zipped) folder, then attach the *.zip file on your next reply.
Looking forward to your feedback.
