Can not install modules in Node-Red Addon ETIMEDOUT

General
1

Hello, I m new at the forum and after some research I was not able to solve my problem in HAOS and Node Red Addon.
My hardware is a Asus N100 board with 16 GB RAM and several SSDs. There is TrueNAS Scale installed and HAOS on a VM in there. This is running well so far but I want to use Node Red and installed it as an Addon in HA.
So now the problem, as I want to install some additional Addons like KNX or else I got the error message

Probably there is a connectivity problem or Node red could not connect to the internet but all other Addons have internet access, also HA is well connected. Is there any further setting or so? Node Red settings are as follow

It seems that only the installation is not working. The available modules will be listed and there are more available since yesterday. How can I install these modules :grin:

Hi. Welcome to the forum.

You may or may not be aware that HA runs node-red in a docker container.

Containers are isolated from the OS and without proper configure can suffer network connectivity problems.

Unfortunately node-red has no control over this - the container is set up by HA.

I'm afraid this problem you have cannot be fixed by changing any settings in node-red - it lies somewhere between your hardware and HA.

Searching your issue on Google lead me to your duplicate post on the HA forum and this similar post: NodeRed in Home Assistant no longer can install pallets or update, seems to be offline. npm ERR! network ‘proxy’ config is set properly - Node-RED - Home Assistant Community it looks like the same issue you have. Did you disable IPV6 as instructed?

I had this issue and found by going into Home Assistant\Settings\System\Network\Configure network interfaces and disable IPv6, save, restart Home Assistant, everything started working again

Hi Steve-Mcl,
you are genious. Thank you for that hint. It is working right now. I was disabling IPv6 and all is working. I didnt found the post you mentioned before.
