Error listner

[Spider1097]

When i run listner:
#!/usr/bin/env python

import asyncio
import techmanpy
from std_msgs.msg import Int32MultiArray
import rospy
from geometry_msgs.msg import PoseStamped
import numpy as np
import signal
import time

class ArmControl:
def init(self):
self.marker_pose=None
self.move_axis_vec=[0, 0, 0, 0, 0, 0]
self.step_m=400
self.step_r=10
self.marker_approached_rot=True
self.marker_approached_pose_xy=True
self.marker_approached_dist=True
self.reseted=False

	self.turn_motors=[0, 0, 0, 0, 0, 0]
	self.selected_motor = 0
	self.actual_position = [0, 0, 0, 0, 0, 0]

	self.zgoda = 1
	self.ip = "192.168.10.2" #ip do połączenia z manipulatorem
	self.mode = 0

async def move_to_point(move_axis_vec):
async with techmanpy.connect_sct(robot_ip=ac.ip) as conn:
conn.add_broadcast_callback(print)
#await conn.stop_motion()
await conn.move_to_joint_angles_ptp(move_axis_vec, 0.5, 10)#
await conn.set_queue_tag(1)
tag_status=1

async def listen():
async with techmanpy.connect_svr(robot_ip=ac.ip) as conns:
conns.add_broadcast_callback(print)
await keep_alive()

ac=ArmControl()
czas = 5

while(1):
asyncio.run(move_to_point([135,-32,69,-37,94,-15]))
time.sleep(czas)
asyncio.run(move_to_point([150, -32, 69, -37, 94, -15]))
time.sleep(czas)
asyncio.run(listen())
time.sleep(czas)

i got that issue:

Traceback (most recent call last):
File "listner.py", line 54, in

File "/usr/lib/python3.8/asyncio/runners.py", line 44, in run

except asyncio.TimeoutError: raise TMConnectError(None, msg=f'Opening connection timed out after {self._conn_timeout} seconds') from None

What can be wrong, i trying solve this problem 5 days?
