Device offline on web dashboard and cli

After placing an Intel NUC device on the production site, the device went offline on the web dashboard and cli, but the device is still reporting logs, deploys container updates, shows the correct container status…

How can I debug this? I suspect the device is not capable of connecting to the vpn service, but it would be useful to check this assumption somewhere on the device.

That sounds like it. Do you happen to have another device in the same network that we can use to hop through and investigate this issue? Otherwise, are you able to deploy one for debugging purposes?

Currently there is not another balena device on the site, but we will install one in the near future. Thanks!

Also, was the device showing connected before and dropped out of nowhere? If yes, are you aware of any changes on the local network side (especially firewall related)?
