I have to connect to a remote sftp server to upload some files using python 2.7. i have been given a username, password and the authentication key file. when i execute this code: 

srv= pysftp.Connection(host='54.172.33.121',username='xxx',password='xxx',private_key='c:\SFTPKey\hajjcoreit.ppk')

i get this error:

BadAuthenticationType: ('Bad authentication type', [u'publickey']) (allowed_types=[u'publickey'])

i can access the server through winSCP though.

Edits in your code

You probably have done something wrong with the hostname. As the proper syntax for pysftp is as

import pysftp
sftp = pysftp.Connection('hostname', username='me', password='secret')
#
# ... do sftp operations
#
sftp.close()    # close your connection to hostname

so now this is what you do,

srv=pysftp.Connection('sftp.54.172.33.121',username='xxx',password='xxx',private_key='c:\SFTPKey\hajjcoreit.ppk')

so you won't get any error.Also cross check with the filezilla that the link, uid and password are correct.
