Python HTTPS connection

Hello,

I am having some issues to work with the python API to connect to the controllers. So far I was connecting using a cluster account. I am using Python 3.4 on a CENTOS 7.2 server using 5.4P1 MNSDK.

While opening a HTTPS connection I get:

Traceback (most recent call last):
File "netappops.py", line 304, in <module>
a.GetSnapshotsList()
File "netappops.py", line 275, in GetSnapshotsList
raise StorageException("query failed: reason %s error number: %s ", resp.results_reason(),resp.results_errno())
__main__.StorageException: ('query failed: reason %s error number: %s ', '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:600)', 13001)

On the controllers I have a self-signed certificate. This error is despite I dont want to do an host or server verification: NaServer methods:

def is_server_cert_verification_enabled(self):

def is_hostname_verification_enabled(self):

return false.

I have solved the first problem adding the selfsigned certificate to my CA chain.

Now I try to connect to the vserver management IP, and I get:

Traceback (most recent call last):
File "netappops.py", line 306, in <module>

File "netappops.py", line 274, in GetSnapshotsList

% (hostname, dnsnames[0]))
ssl.CertificateError: hostname 'dbnasc501-mgmt02.cern.ch' doesn't match 'vs2sx50'

Again I dont want to do any SSL verification. Is no otherway that to create a certificate (and DNS entry) with the vs2sx50 (this is my vserver name) on it?

Thank you.

Have you tried

import ssl
ssl._create_default_https_context = ssl._create_unverified_context

to disable certificate verification?
