Error: unable to perform an operation on node 'rabbit@DESKTOP-M39P0B3'. Please see diagnostics information and suggestions below.


Most common reasons for this are:


 * Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
 * CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
 * Target node is not running


In addition to the diagnostics info below:


 * See the CLI, clustering and networking guides on http://rabbitmq.com/documentation.html to learn more
 * Consult server logs on node rabbit@DESKTOP-M39P0B3
