hass_pyscript_kernel: unable to connect to host localhost:8123

[javixeneize]

Hi

When running a pyscript in a jupyter notebook, i have this error

hass_pyscript_kernel: unable to connect to host localhost:8123 (Multiple exceptions: [Errno 111] Connect call failed ('::1', 8123, 0, 0), [Errno 111] Connect call failed ('127.0.0.1', 8123))

After 5 attempts, it tries to connect to the kernel and it gives a 404

I think the problem is jupyter runs as a container and cant resolve home assistant as localhost, but i have no idea where to change that configuration

Any suggestion?

Thanks
