Connected Failsafe (Waiting for Serial Data)

Hi I am stuck and can't get my setup to work, it would be great if you could help me.

I am trying to use a the vJoySerialFeeder to connect my Flysky radio to my PC.

When I want to connect my Arduino through the correct COM port, I get the message Connected, Failsafe (Waiting for Serial Data).

I am usind a Arduino Nano and a Flysky IBUS receiver (FS-A8S V2).

I don't know what is going wrong and I couldn't find any solutions...

Thanks for helping me out and I am looking forward for suggestions.
