Error using Python NMSDK 5.4 to connect to OnCommand 6.3

I'm trying to get a connection working through the Python SDK to OnCommand 6.3 . I believe we are running on the appliance. When I run the below script (essentially the hello world script in the documentation), I get this error: "Failed [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)"

Script (with host/username/password blocked out):

dfmserver = 'xxxxxx' #OnCommand 6.3
dfmuser = 'xxxxxx'
dfmpw = 'xxxxxx'
s = NaServer(dfmserver, 1, 0)
s.set_style('LOGIN')
s.set_transport_type('HTTPS')
s.set_server_type('DFM')
s.set_port(443)
s.set_admin_user(dfmuser, dfmpw)

output = s.invoke("dfm-about")

if(output.results_errno() != 0😞
    r = output.results_reason()
    print("Failed " + str(r) + "\n")

else :
    r = output.child_get_string("version")
    print("Hello World ! DFM Server version is: " + r + "\n")

Given that I'm not using a certificate to connect, I wonderif this is an OnCommand setting that needs to be tweaked. Any suggestions?

Hi,

I experienced the same.

Patch NaServer.py adding following code at line 41

#Patch Verification Certificate Fail
ssl._create_default_https_context = ssl._create_unverified_context

François
