nRF Connect (v3.6.1) error message: ""Failed to setup device: No serial port available for device with serial number xxxxxxxx""

I was using nRF Connect (v3.6.1) to communicate to Segger J-link Base (version 11.0) but it failed. The error message was: ""Failed to setup device: No serial port available for device with serial number xxxxxxxx"". Anyone has an idea how to fix this issue? Thanks!

Thanks for quick response! I was using Bluetooth Low Energy App and nRF52 chip was connected to J-Link. The app detected the J-Link Base but when I clicked it the error message showed up.
