Python3 exchangelib connect error: _ssl.c:749?
I am trying to connect to my company's Exchange server with exchangelib.
I want to see all the mails I have received on MS Exchange / OWA.
When I run the code below, I get:

from exchangelib import DELEGATE, Account, Credentials,NTLM,Configuration,Version,Build

from exchangelib.protocol import BaseProtocol, NoVerifyHTTPAdapter
BaseProtocol.HTTP_ADAPTER_CLS = NoVerifyHTTPAdapter
Can you please let me know how to use certificates with exchangelib?
How to fix it?
Thanks for your help!
Have you tried disabling ssl verification in your config ?
config = Configuration(service_endpoint ='...', credentials=credentials, auth_type=NTLM, verify_ssl=False)
The sources seem to talk about a parameter like this.

I tried connecting to opensearch using python client but getting SSL Error.
OpenSearch Version: 2.0.1
Python Version:3.6
public IP of the opensearch host: 10.83.5.67
Here is the python code for connecting the client to opensearch:
from opensearchpy import *
host = '10.83.5.67'
port = 9200
auth = ('admin', 'admin') # For testing only. Don't store credentials in code.
ca_certs_path = '/etc/opensearch/cert.pem' # Provide a CA bundle if you use intermediate CAs with your root CA.
# Create the client with SSL/TLS enabled, but hostname verification disabled.
client = OpenSearch(
hosts = [{'host': host, 'port': port}],
http_compress = True, # enables gzip compression for request bodies
http_auth = auth,
use_ssl = True,
verify_certs = True,
ssl_assert_hostname = False,
ssl_show_warn = False,
ca_certs = ca_certs_path
)
The certificates used in opensearch.yml file are:
plugins.security.ssl.transport.pemcert_filepath: /etc/opensearch/cert.pem
plugins.security.ssl.transport.pemkey_filepath: /etc/opensearch/privkey.pem

plugins.security.ssl.http.pemkey_filepath: /etc/opensearch/privkey.pem
plugins.security.ssl.http.pemtrustedcas_filepath: /etc/opensearch/fullchain.pem
This is the error I am getting:

Not sure what's wrong I am using the same certificate in opensearch-dashboard.yml file, but can't connect using python client.
Any suggestion would be really helpful.
Thanks
I'm sending a simple 'post' request through the 'requests' module. It works fine when execute it directly through the linux terminal. However, when I set it up through the crontab, the log is indicating and error.
If I execute the below through the terminal, it works fine.
'/usr/bin/python3.6 /location/sa/tb/uc/md/se/sea.py'
If I setup the crontab as follows, I get an error.
/usr/bin/python3.6 /location/sa/tb/uc/md/se/sea.py >> ~/Test_log.log 2>&1
Below is the error message:

What did I try?
Tried adding absolute path inside the script.
Added a proxy to the headers, but no go.
Any help would be appreciated.
Some servers don't start re-listen immediately (check_mk flag), while calling multiple requests from a single connection. One of the reason is to avoid DoS attacks and service availability to all users.
Since your crontab made your script to call the same API multiple times using a single connection, I'd suggest you to add a void timer before making a request, e.g. add time.sleep(0.01) just before calling the API.
I'm new to coding and have been stuck at one point trying to download an mp3 file.
I can access the file but not download it; it produces a variety of problems while executing this code's downloading mp3 file portion. Please, could you assist me?

The issue you're facing is due to the missing certificates of the python library causing issues with the urllib. Please refer to the below url in order to resolve the certificate issue :

I don't know how to solve this issue. Maybe it's because I worked behind a proxy? If so, how to make urllib.urlretrieve work behind the proxy?
Add proxy settings to your global environment to see if it fixes the problem.
sudo gedit /etc/environment
Then add these two lines
http_proxy=http://your_proxy.com:443
https_proxy=https://your_proxy.com:443
import requests
spiders = requests.get('https://en.wikipedia.org/w/api.php')
print(spiders)

Even when I have followed some tutorial verbatim I have encountered this issue when the instructor would have access w/o issue. Any ideas?
u can ignore SSL like this:
import requests
spiders = requests.get('https://en.wikipedia.org/w/api.php',verify = False)
print(spiders)
other solution:
from urllib.request import Request, urlopen
rq = Request('https://en.wikipedia.org/w/api.php')
response = urlopen(rq).read()
