# How to solve action client not connected?

Does anyone know how to solve error action client not connected?

The error text is:

[ WARN] [1559064181.400017201, 235.919000000]: Waiting for arm_controller_moveit/joint_trajectory_action to come up
[ WARN] [1559064188.755204272, 241.920000000]: Waiting for arm_controller_moveit/joint_trajectory_action to come up
[ERROR] [1559064196.377289892, 247.920000000]: Action client not connected: arm_controller_moveit/joint_trajectory_action


When I try to see all action servers with the command:

rostopic list | grep -i goal


This is output:

 /execute_trajectory/goal
/joint_trajectory_action/goal
/move_base_simple/goal
/move_group/goal
/pickup/goal
/place/goal


I am using joint_trajectory_action action server, but I tried with other and it is not working.

Any help would be appreciated. Thanks in advance!
