I can't connect to my Raspberry Pi 4 via SSH (Putty)!

hp1 · July 18, 2021, 11:05am

I have Home Assistant in a Raspberry Pi 4. HAss is working fine and I can connect it local (homeassistant:8123 or with my internal IP:8123) and remotely (Nabu Casa). But every time I try to login in my Raspberry pi via Putty, I get this message: “Network error: Connection refuse”. What could be the problem? I have always been able to login to my Raspberry pi via Putty.

Assuming you are using Home Assistant OS…
Did you install and start the SSH addon?

Hey!

I saw this soulution for using putty

# Home Assistant Add-on: Terminal & SSH

## Installation

Follow these steps to get the add-on installed on your system:

1. This add-on is only visible to "Advanced Mode" users. To enable advanced mode, go to **Profile** -> and turn on **Advanced Mode**.
2. Navigate in your Home Assistant frontend to **Settings** -> **Add-ons** -> **Add-on store**.
3. Find the "Terminal & SSH" add-on and click it.
4. Click on the "INSTALL" button.

## How to use

This add-on adds two main features to your Home Assistant installation:

- a web terminal that you can use from your browser, and
- enable connecting to your system using an SSH client.

Regardless of how you connect (using the web terminal or using an SSH client), you end up in this add-on's container. The Home Assistant configuration
directory is located on the path `/config`.

I’d like to update und upgrade the raspberry. This is not possible with the

sudo apt-get update
sudo apt-get upgrade

in a terminal session with the plugin?

That is not how you update Home Assistant OS.

You will be notified when there is an OS upgrade to install from the UI.

Sorry! As a noob - I mean to update the OS … ; )

Yes, that is what I said, you don’t do that with apt-get for HA OS.
