How to Handel exception during Mysql connection

I m trying to connect to a mysql database. if server is not responding, my application crashes. I am using try, except but looks like two exceptions are raising and "try: except" could not handle it. can some one figure it out where is the problem. below is my code:-
def check_server(server_address):
con = mysql.connector.connect(host='{}'.format(server_address),
database='domicile_reports',
user='xyz',
password='xyz')
try:
if con.is_connected():
print('{} Connected'.format(server_address))
con.close()
except Exception as e:
print("Can not connect to db. {} Occured".format(e))
check_server('25.13.253.67')
Error displayed on terminal:-
Traceback (most recent call last):

network.py", line 574, in open_connection

You need to put the connect() call inside the try: except block. You can also use a context manager to properly close the connection, example:
import mysql.connector
from mysql.connector.errors import Error
def check_server(server_address):
try:
with mysql.connector.connect(
host=server_address,
database="domicile_reports",
user="xyz",
password="xyz",
) as cnx:
print(f"{server_address} Connected")
except Error as err:
print(f"Can not connect to db. {err} Occured")
check_server("25.13.253.67")

Can't connect to MySQL server on 'localhost:3306' (10061) During handling of the above exception in python

i wrote a program to check if program can make connection to MySQL server and if cant connect to server print a error message and this is the program that i wrote
import mysql.connector
is_connected = False
def check_connection():
global is_connected
try:
db = mysql.connector.connect(
host="localhost",
user="root",
passwd=""
)
if db.is_connected():
print("Connected to MySQL database")
is_connected = True
except:
print("Unable to connect to MySQL database check if mysql server is running on defaul port which is 3306")
return is_connected
the whole objective here is print a error message when MySQL server is not running so i stop the server and run the file it works fine when in its own file but when it import to another file and call the check_cconnection method its give this error

PyMySQL:- OperationalError: (2003, "Can't connect to MySQL server on 'localhost' ([Errno 111] Connection refused)")

I am trying to run a scrapy spider and whenever the spider opens/scrapes/closes I am saving data to a pymysql database. When I was running on RDS it was not giving any kind of error, however when I switched to my localhost it is giving me a 'Connection refused error'.
Here's the code for my runner.py file
import pymysql
connection = pymysql.connect(
host='127.0.0.1',
port='3306',
user='root',
password='lifeisgood',
db='scrapy_dev'
)
# rest of code
and here's the complete stacktrace of the error:

I've tried ways by looking at other stackoverflow answers but none of them helped so far.
Please help me.

Take a closer look at the configuration. It must be a configuration problem. Please check the remote code is not synchronized!

Python myqsl.connector connection error on pyton.org

I have a mysql server on my computer. I did port fowarding on my modem. I checked port is open or not with signal sites and return success answer. When i try connect on my pc with host = "localhost" i returned success answer. But when i try connect mysql server with python.org's shell, i returned connection error same like this:

How can i connect my mysql server ?

In order to encounter this error first do the following:
Make sure the host is in the format 127.0.0.1 and there are no / or \ in the host name
Check if you have specified all the correct info about the server like passwords, user, root, etc
Make sure the server is active and there is no fire wall blocking your access
Remove all the unwanted users from the server

Trouble establishing connection to server with PyMySQL [WinError 10054]

Pretty new to both Python and SQL, so please excuse my noobishness. We have a server at my company that I'm trying to connect to through some python code. I have the correct IP address and logon credentials, and I can connect to it in SQL Server Management Studio without any issues, but I can't connect to it through PyCharm's database feature or through my code. I'm running python 3.6 if that makes a difference.
This is the code that I'm running (I've omitted the server ip address and logon credentials for security):
import pymysql
db = pymysql.connect(host='server ip',
port=1433,
user='username',
passwd='password',
db='Development DB')
cursor = db.cursor()
cursor.execute("SELECT VERSION()")
data = cursor.fetchone()
print("Database version : %s" % data)
db.close()
When I run the code, after about 2 minutes of nothing happening I get this error:
Traceback (most recent call last):
File "C:\Program Files\Python35\lib\site-packages\pymysql\connections.py", line 1021, in _read_bytes

From what I can understand, it looks like a connection was established, but the server forced it to close after a while. Can anyone offer me some more insight into what the problem might be? Thanks in advance!

As I wrote in another post, you may want to try using pymssql, in case your database is not a MySQL DB but a Microsoft SQL DB.
