Re: [sumo-user] Connection refused to traci

[Harald Schaefer <fechsaer@xxxxxxxxx>]

Hi Valentin,

some questions:

a) Are the traci-client and the sumo-server running in the same container?

b) if not can the port of the sumo-server be reached across container borders?

c) Did you start the server before you start traci (traci.start(...))

d) have you looked into your system log files (like journalctl --since "5 min ago")

Greetings, Harald

Hey I am still having the same issue. I tried it in a container on a different system and again, the same issue... 

Could not connect to TraCI server at localhost:59057 [Errno 111] Connection refused
 Retrying in 6 seconds

This is what I get all the time and I am out of ideas how to solve the issue.

I would really appreciate any ideas and help.

Thanks a lot in advance.

BR,

Valentin

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!

Valentin
