rdp2tcp.exe: the request is not supported

[eksapetm]

Hi,
Today I learned about this project and I tried to compile it. I then ran the rdp2tcp.exe on a Windows Server 2019 system, and it returned the following error:

C:\Users\eksapetm>rdp2tcp.exe
error: WTSVirtualChannelOpen (50: The request is not supported. )

Assertion failed! 

Program: C:\Users\eksapetm\rdp2tcp.exe
File: aio.c, Line 77

Expression: valid_aio(rio) && valid_aio(wio)
Assertion failed!

Program: C:\Users\eksapetm\rdp2tcp.exe
File: aio.c, Line 77

Expression: valid_aio(rio) && valid_aio(wio)

Is this a known issue? Is it supposed to work on Windows 2019 Server? Or did the administrator prohibit it using a policy?

Thanks,

eksapetm.

I apologize, I thought I had to start rdp2tcp.exe prior to connecting with FreeRDP using the /rdp2tcp: argument. Now that I first set up the rdp connection that way it works after all.
