Hi @jacques7zhu,
Welcome to the forums!
It seems like the device cannot establish a VPN connection. I can’t determine the exact reason, because the lines in vpn logs are truncated, but it seems like a TCP connection could be established but, after that the connection fails. I can’t find any indication, that the device reaches our cloud system though, so it seems like the connection is probably intercepted somewhere on the way. Maybe there is a firewall trying to perform deep packet inspection on that network?
When you write you can access it from another device on the same network, do you mean your Laptop or another balena device on the same network? If there is an online balena device on that same network could you grant us support access and point us to the device, then we can also access the non functioning one and dig deeper.
