This is where reading the official documentation helps, [A tour of thin-edge.io | Thin-edge](https://thin-edge.github.io/thin-edge.io/next/start/getting-started/)

But in short, you can run the commands I posted earlier:

```sh
sudo tedge disconnect c8y
sudo tedge connect c8y

```

Here is the outcome

```auto
sudo tedge connect c8y

Checking if systemd is available.

Validating the bridge certificates.

I would just suggest going through the getting started document steps again.

But I’ll have to let someone else take over for the moment.
