shell_bt_nus, not able to connect to network port

[Herre Vermeer]

I am following the instructions to set up NUS shell through bluetooth with the following example: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/bluetooth/shell_bt_nus/README.html#testing-using-the-bluetooth-le-console but when opening a new session with Putty to 127.0.0.1:8889 it gives the following error: 'Unable to open connection to 127.0.0.1. Network error: cannot assign requested address.'

Is there a reason why this might give me this error after all steps were followed through without errors, and when it even worked before?

Hi,

Could you please describe your working environment (operating system, devices, versions ...)? 

Since it worked before, which changes have been made so that the sample does not work anymore?

Best regards,
Dejan
