Question I want to be able to connect to and download a file from my remote FTP filezilla. I am able to connect however as soon as it executes "ftp.retrlines('LIST')" I get an error as described below. Any help would be greatly appreciated!!!
Here is my script
from ftplib import FTP_TLS
ftp = FTP_TLS('111.111.111.111) # Hidden IP for my FTP SERVER
ftp.login('ftpuser', 'ftppassword12345')
ftp.prot_p() # securing data connection explicitly
ftp.cwd('/') # change working directory to the root
ftp.retrlines('LIST') # This is where it fails
Here is the error
Traceback (most recent call last):

I am trying to connect to a Postgres Database using sockets to enforce a particular TLS version from the client in order to verify that the Database does not accept connections from the client which uses an older version of TLS like tlsv1.1. The connection is failing on handshake with the following error :
python test2.py

I need to connect to Kafka broker in python using SASL/SCRAM-SHA-256 authentication.
I use the kafka-python (2.0.1) python library which allows this kind of connection/authentication.
This is an example of code, but i get the error ... not Brokers available
prod = KafkaProducer(bootstrap_servers='server:9093',
security_protocol='SASL_SSL',
ssl_certfile='path to ca in pem format',
sasl_mechanism='SCRAM-SHA-256',

Getting the following error

i'm getting the title error when I'm trying to access my gmail emails using the imap-tools module of python. Below is the details as given during establishing the connection.

I think the error is because of my gmail email secured with 2-step authentication. I want to keep my security for my gmail account same want to know a workaround to access my emails from my python program.
Here is my python code:
from imap_tools import MailBox
gautham_gmail_box = MailBox('imap.gmail.com')
gautham_gmail_box.login('my_email#gmail.com','my_password')
I think you have to enable some unsecure access to your Gmail before you can access it this way, but I'm not sure.
IMO, you're much better off using Google's official library to access Gmail using Python. Visit https://developers.google.com/gmail/api/quickstart/python to learn more about this.

I am not using any proxy server.
Help me to debug this code.Thanks in advance.
Your code is perfectly fine.
The error is a timeout, which suggests a networking issue, such as a port being blocked by corporate IT.
Try it from another network (eg from home) and you'll find that it will work correctly. It is then a matter of tracking down whoever runs your network to figure out what is blocking your connection.
Alternatively, create an Amazon EC2 instance, connect to it (if possible), and run your code from there.
I am new to Python and trying to run attached code.

Earlier I thought that it is may be because I am running the script from my office and VPN is causing issues. So I ran it from my home internet connection but no resolution :(
