Hello, while I'm trying to run any example, I'm getting the following error-

Traceback (most recent call last):
File "", line 2, in
File "umail.py", line 30, in init
OSError: -202

my code-

import umail
smtp = umail.SMTP('smtp.gmail.com', 587, username='my@gmail.com', password='mypassword')
smtp.to('someones@gmail.com')
smtp.send("This is an example.")
smtp.quit()

Please ,help me to solve this. Thanks in advance

The OSError: -202 was solved. I had just entered some new codes to connect to the wifi and the error's gone.
