Error When Writing to SQL Table - skaailet - Jun-09-2020

Im getting an error "the machine refuses it" when running my script to write to a table
from pylogix import PLC
import sys
sys.path.append('..')
import time
import pymysql

with PLC() as comm:
    comm.IPAddress = '172.21.12.10'
    comm.ProcessorSlot = 0
    ret = comm.GetPLCTime()
    print( "Fecha y Hora de Registro Revision Fallas", ret.Value)
    time.sleep(1)
    Estacion = "D2R_030"
    print("Connecting To Database")

    connection = pymysql.connect(host='ACTWSLT01',
                             user='METALSA\satmslt',
                             password='T$m@l19*',
                             db='Python_PLC')
    cursor = connection.cursor()
    print("Connected")

#------------------------------------------------------------------------------------------ ESTACION D2R_030 -------------------------------------------------------------------------------#
    print("INICIO DE REVISION ESTACION :" , Estacion)
#ACTUADOR 1 
    ACTUADOR = comm.Read('D2R_030.Status.Act._1.WBypassed')
    ret = comm.GetPLCTime()
    Numero_Act_EnBypass = 0
    
    if ACTUADOR.Value == True:
        Sensor = "ACTUADOR 1 WORK SENSOR EN BY PASS"
        Numero_Act_EnBypass= (Numero_Act_EnBypass+1)
        sql = "INSERT INTO 'PLC Actuadores' ('Id', 'IP', 'Date', 'Estacion', 'Tag', 'Value') VALUES (%s, %s, %s, %s, %s)"
        cursor.execute(sql,(comm.IPAddress, ret.Value, Estacion, ACTUADOR, Sensor))
        plc_data = plc_data.append(temp_dict.copy(), ignore_index=True)
        plc_data.to_excel("Actuadores.xlsx", sheet_name='Result', index=False) 
        print(Sensor)
        connection.commit()

    else:
        Sensor = "ACTUADOR 1 WORK OK" 
        print(Sensor)

    comm._closeConnection
    connection.close()
    print("Terminado")

It's saying the python script tried to connect to the mysql server and wasn't able to. Could be access restrictions or firewalls.
