[sumo-user] Connection refused to traci

[Valentin Düe <valentin.duee@xxxxxxxxx>]

I am currently trying to run traci in a container and get a connection error:

ConnectionRefusedError                    Traceback (most recent call last)
.../traci/__init__.py in connect(port, numRetries, host, proc)
     67         try:
---> 68             return Connection(host, port, proc)
     69         except socket.error as e:.../traci/connection.py in __init__(self, host, port, process)
     53             self._socket.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1)
---> 54             self._socket.connect((host, port))
     55             self._process = processConnectionRefusedError: [Errno 111] Connection refused

I really don't understand how this happens. What can be reasons for getting a refused connection?

Best regards and thanks for your help!
