Getting "socket.error: [Errno 54] Connection reset by peer" when trying to connect to REST API using Python lib

[DVGeoffrey]

I'm trying to connect to the Splunk REST API and am running into errors. Not sure what to do from here...
Code:

import splunklib.client as client

service = client.connect(
    host="192.168.50.251",
    scheme="http",
    username="username",
    password="password"
)

I am able to log into the Splunk web interface using these credentials, but when trying with the python API I get:

Traceback (most recent call last):
  File "splunk_testing.py", line 9, in <module>
    password="dev"

socket.error: [Errno 54] Connection reset by peer

We're running Splunk 6.3.0 and I'm using splunk-sdk (Py lib) v1.5.0. The management port is set to 8089, so I think this should work. Am I doing something wrong?

Answering my own question... I was using the wrong scheme. Switched to "https" and it's now working. This is despite the fact that the "Enable SSL (HTTPS) in Splunk Web?" option is set to "No".
