Connection error

raffi

Hello.

I am trying to get artiq up and running on a new system and am running into a confusing connection error. When I try and run a simple script, even something as simple as led.py, kernel's won't execute. The scripts get hung trying to connect to the system and I am not sure why. I can ping my system and generated the device_db from artiq.frontend.artiq_ddb_template file.json. I made a very simple json file that I am pretty sure is correct. Any thoughts on what causes this or how to fix would be greatly appreciate. I copied the trace back below.

Also post your device_db.py and the ARTIQ Python you're trying to run. Post a transcript of what you see on core device log. https://m-labs.hk/artiq/manual/utilities.html#core-device-management-tool
