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)"

I have the same problem

trying to attach file..

here my diag file

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.

Hi, I got a same problem. However, I clean uninstall splashtop but even after that, my android still cannot connect to my laptop. If I try to connect on my PC (other spacedesk), it works just fine. I also did uninstall and reinstall spacedesk and updated to the newest version so as well in my android. I don't get error message on my laptop but the one on my android is like this:

Disconnected by server error
Error Code: 2-5
Error Info: 0-5
Connected Time: 00:00:01

No error signs in primary device (laptop), just ON (idle)

I didn't see this thread continue as folks here are not posting the debug report. But here I am, you can analyze my debug report after I recreated the issue.

Here's the link: removed link

I regret installing splashtop

weird, I cannot find attachment in this thread, can someone screenshot where the attachment is? The links to the report is removed by the site.

Here you go, I guess you might also need the debug report file so I attached both dxdiag and debug report as well.

I have the same problem. Then updated to Win10 driver to 9.78 and checked that the Android version is current (it is). Still the same problem as described in this post.

Hi, I have gotten the same problem as RichoLA

Hi @djeez2 and @jefftheman,

Hi @ricohla,
Thanks for sending the requested files.
Based on your dxdiag info, you still have splashtop driver installed on your primary machine.
Please uninstall it then reboot your primary machine then try again with spacedesk.

Hi, thank you for your assistance. I realized something is not quite solved yet after I uninstalled and clean uninstalled splashtop. Turns out, splashtop hid its descendants on my system.

If you didn't tell me there's still splashtop driver hidden on my system, my problem probably won't be solved. Thanks to your callout, I managed to track down the driver, its called LUMINONCORE. If any of you guys still cannot connect spacedesk after uninstalling Splashtop, make sure to go to device manager, and delete these drivers and it's software (anything related to Luminoncore/Splashtop).

There are several splashtop drivers installed in your PC, so make sure you check all the driver category, else it won't work. Then restart your PC after you get rid of them, and you're good to go. I have to restart my PC three times in order to make the spacedesk works. 

Hi @djeez2

Thanks for this additional info.

To add to this: it could be related to the latest NVidia drivers. Because the instructions suggested to use the latest ones I installed those. However, I had other problems with the NVidia drivers so I reverted back to 460.79 and that solved my problems. Maybe that is the reason that Spacedesk now "suddenly" works?

Maybe..? we are not sure. But as soon as you encounter the issue again just use the diagnostic file to collect the debug traces so that we can check what is really happening during this problem.
