Still doesn’t seem to work…
Please can you share your workflow in a code block. Im suspecting you have not followed the guide on the breaking changes in python
Thanks Wouter, I’m using n8n v2.2.3 with Ubuntu. I used your config, but unfortunately both JavaScript and Python code nodes are timing out.
So this looks more like a container/env config error. Both the n8n-main and n8n-runners containers are up:

The n8n-main container is on ports "5678:5678". The runners broker listen address is 0.0.0.0, and the runner task broker URI is http://n8n-main:5679. I also added the volume for the runner container.

Are there any network/VPN/container related issues that could prevent access to the runner container?
My VPN was just preventing hostname resolution, which caused the task runners to be stuck waiting. I specified the proxy explicitly and now both python and javascript work well.

I was able to resolve it for myself as well. I added both the main and runner to the same n8n network.

OP, try adding this inside your task-runners service.
