Comment 17 for bug 1563483

Hi all,
Quite new on MaaS, but I think I'm facing the same issue.

Recently rebooted my maas controller (all-in-one installation) after kernel update (which requierd reboot) and suddently the maas-rackd cannot is rejected when it's trying to connect to the maas-region.

Not sure what information I can provide. Few things:
[version]
gdupont@ubuntu-maas:~$ sudo apt-cache policy maas
