I have tried:
except URLError:
...
and also
except urllib.error.URLError:
But known of them is giving the error, just printing the above traceback.
How should I catch the error?
Try this, it's works for me:
import urllib.error
...
try:
post = urllib.request.urlopen(request)
print(post.__dict__)
except urllib.error.HTTPError as e:
print(e.__dict__)
except urllib.error.URLError as e:
print(e.__dict__)
I hope it works for you.

When I import "mysql.connector" firstly, it always failed with SSL error.
here is my simple code test:
import mysql.connector
from wordpress_xmlrpc import Client, WordPressPost
Client('https://mywordpress/xmlrpc.php','user','password')
and here is the error:

But,when I import "mysql.connector" after that,like this:
from wordpress_xmlrpc import Client, WordPressPost
import mysql.connector
Client('https://mywordpress/xmlrpc.php','user','password')
Everything is OK.
Which is really strange!
Can you help me...Thanks!

As far as I know it says no internet connection, but my internet is working fine. So why python is throwing this error?
You can increase the timeout with (in seconds):
requests.get('http://www.gutenberg.org/cache/epub/1112/pg1112.txt', timeout=30)
Found answer using alpbert help and this thread Proxies with Python 'Requests' module
I dont have any proxy but python was still trying to detect a proxy. So i created a dict element
proxies={'http':''}
then this command worked
res = requests.get('http://www.gutenberg.org/cache/epub/1112/pg1112.txt',proxies=proxies)
