I am getting an error when downloading an image using the Balena CLI:

```auto
balena os download raspberry-pi2 -o here1
Getting device operating system for raspberry-pi2
OS version not specified: using latest stable version
Downloading Device OS [========================] 100% eta 47s

```

Raspberry Pi 4 seemed to complete ok, although it does appear to be somewhat intermittent as later the raspberry-pi image succeeded:

```auto
balena os download raspberrypi4-64 -o here5

Getting device operating system for raspberrypi4-64

OS version not specified: using latest stable version

Downloading Device OS [========================] 100% eta 0s

The image was downloaded successfully

```

This issue initially occurred with my GitHub workflows (CLI - 12.45.2) about 12 hours ago. I then tested each image individually about 10 min ago on my Mac and getting the same issue (CLI - 12.44.16). Everything had worked fine until today.

Downloads are also incredibly slow (eta 6m27s for the fincm3 using a 1GB connection in Canada). Are there server issues?

Hello

I’ve just tried some of these downloads using balena CLI v12.47.0 and didn’t encounter any problems. I guess that this may have been a network issue somewhere, but I can’t find any evidence of server problems. In future you can check the status of Balena systems [here](https://status.balena.io/)

Regards - Mark

It started working again around 36 hours after the initial post.

I had checked the Balena systems status at the time, and was green across the board.

Will leave it to you guys whether you want to investigate further.

Thanks for getting back on it.
