My USB port doesn't work well so I use WiFi ADB app on my Android phone and I do this when this error occur:
- turn off the WiFi ADB
- disconnect from the WiFi
- turn off the Mobile Hotspot
- unplug Ethernet cable
- plug Ethernet cable
- turn on the Mobile Hotspot
- connect to the WiFi
- turn on the WiFi ADB
- turn off the WiFi ADB
- turn on the WiFi ADB (yes second time)
- run command: adb kill-server
- run command: adb connect 192.168.137.2
