Modbus Error: [Connection] Failed to connect[ModbusSerialClient(rtu baud[115200])]

whenever I try to connect the gello with the UR5e arm, I run into this error: in ur robot in ur robot in ur robot in ur robot Unable to connect to /tmp/ttyUR Traceback (most recent call last): File "/home/kholoudbashayan/GitHub/gello_software/gello/robots/robotiq_gripper.py", line 75, in sendCommand self.client.write_registers(0x03E8, message, unit=0x0009) File "/home/kholoudbashayan/miniconda3/envs/gello/lib/python3.8/site-packages/pymodbus/client/common.py", line 103, in write_registers return self.execute(request) File "/home/kholoudbashayan/miniconda3/envs/gello/lib/python3.8/site-packages/pymodbus/client/sync.py", line 105, in execute raise ConnectionException("Failed to connect[%s]" % (self.str())) pymodbus.exceptions.ConnectionException: Modbus Error: [Connection] Failed to connect[ModbusSerialClient(rtu baud[115200])]

During handling of the above exception, another exception occurred:

Humm I'm not sure about this exact issue. As i have not worked directly with the UR5e robotics. Are you able to run the robotiq_gripper.py as a stand alone script to control just the gripper?
