Hi,
I want to use mender for updating a Yocto based embedded device (Jetson Nano). Somehow the mender-client gets stuck after the network configuration changes. These are the steps:
- Update the network configuration using networkd:
> cat <<EOT >> /run/systemd/network/20-user.network
[Match]
Name=eth0
[Network]
DHCP=yes
EOT
> networkctl reload
- Check for updates:
> mender check-update
Somehow it seems to hang inside the proxy.go. Here is the log:

Calling mender check-update again gives the following output:

After restarting the mender-client service, everything works again, even with the new network configuration.
Is this a bug or am I doing something wrong?
Thanks,
