I get the following error from the ServiceProxy when trying to open an SSH connection. I am running the DeviceProxy and I have confirmed in the Azure portal that the device is reported as 'online' when the proxy is running.

info: ServiceProxy[0]
      Waiting for TCP clients...
info: ServiceProxy[0]
      Accepted TCP client using endpoint '127.0.0.1:2222'.
fail: ServiceProxy[0]

I'm running .NET7.0.

Context

OS: Windows 10 Pro64-Bit-Betriebssystem,
**NET Target Framework :**6.0.300
Device: (Laptop, Raspberry)
SDK version used: 1.27.1.0

Description of the issue

I am trying to set up an SSH channel through a streaming service. For this purpose, I am using Azure C# SDK.
This is done via two APIs:

Service Menager on the user side, which initiates the connection to the streaming service on the hub and addresses it with the device ID. (where I suppose the error lies).

Lisiting and handling API on the device side

it turned out that the streaming request does not reach devices with IDs containing numbers, which causes the connection to Rest Deu to TimeOut Error .
