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

[Fravieror]

Hey team, I'm running the following code:

import signalfx

token = 'my token'

signalflow_program = "my program"
signalflow_client = signalfx.SignalFx().signalflow(token=token, endpoint="my endpoint")
try:
  print('Executing {0} ...'.format(signalflow_program))
  computation = signalflow_client.execute(signalflow_program)
  for msg in computation.stream():
      print("test")
      if isinstance(msg, signalfx.signalflow.messages.DataMessage):
          print('{0}: {1}'.format(msg.logical_timestamp_ms, msg.data))
      if isinstance(msg, signalfx.signalflow.messages.EventMessage):
          print('{0}: {1}'.format(msg.timestamp_ms, msg.properties))
finally:
  signalflow_client.close()

But I'm getting this error:

Using CURL works correctly. Could you shed any light to solve this? Thanks in advance!
