Landscape GUI failed to start after a reboot

Question

I installed Openstack with Ubuntu's Autopilot (openstack-install), and after some fighting, and a lot of help from Ubuntu people, was working fine. Today I needed to reboot everything, and after the reboot, everything seemed to be fine, all services went up nicely, etc. The only problem is when I wanted to go to Landscape's GUI, this is what I get: "Oops!

Sorry for the inconvenience. If you're having trouble filing a support case, please phone us. Support hours are as per your service level agreement."

I restarted apache2 service on Landscape's server (juju-machine-0-lxc-2) and another machine (container) where it has apache2, and it has the IP address where I connect to Landscape's GUI, juju-machine-0-lxc-0. Nothing changed.

/var/log/landscape/sysinfo.log is empty in both containers.

juju says that both services are running fine:

Answer 1

Run this command on both landscape/0 and landscape-msg/0:

sudo lsctl status

Looks like the landscape services are down. Or at least the path from apache to them, which looks like this:

apache ---> haproxy ---> backend services (app, msg, ping, etc)
