After rebooting the computer, sys-firewall stopped starting, showing the error: “Cannot connect to qrexec agent.” At the same time, sys-net seemed to start according to the Qube Manager, but it would shut down after being unable to start sys-firewall.
When attempting to view the logs, they contained only one entry: “Logfile Opened.”
Meanwhile, the following message kept appearing in the dom0 log:
