I have one device where I suspect network issues earlier on today.  
However I can connect well to the device and device seems to connect well to my servers.

I run Device health check, it returns all fine except one:  
check\_networking  
Some networking issues detected: test\_balena\_registry: Could not communicate with for authentication

What it could be? I have restarted container and entire device, yet it persists.

Thank you

Hi. Could you check that the device’s network follows our requirements: [https://www.balena.io/docs/reference/OS/network/2.x/#network-requirements](https://www.balena.io/docs/reference/OS/network/2.x/#network-requirements)
