cannot connect to daemon at tcp:5037: cannot connect to 127.0.0.1:5037:  (10061)

D:\adbtools
 netstat -ano | findstr "5037"

D:\adbtools

what is the reason for this?

Apr.20,2022

refused to connect because the service did not start
you can start the service first and then check: adb start-server

  • daemon not running; starting now at tcp:5037
  • daemon started successfully
