#summary Troubleshooting == General == == Linux OpenVz version == * *Issue:* I start Core and place a host into the GUI and press Start. I get the following error for just doing that {{{ can not find channel named "-1" can not find channel named "-1" }}} also, my console may display this error: {{{ Connecting to 127.0.0.1:4038... Failed to open API channel to 127.0.0.1:4038: couldn't open socket: connection refused }}} * *Resolution:* This suggests that cored was not running or is hung. Try "sudo killall cored", and if no process was killed, check also that there is not a /var/run/cored.pid file lying around. Try restarting cored in verbose mode: "sudo /usr/local/sbin cored -v" and if that works, restart it in daemon mode such as: "sudo /usr/local/sbin/cored -d". Check the log file in /var/log/cored.log if all else fails. == FreeBSD version == Add your content here.
