Stopping and halting node rabbit@DESKTOP-8VB0JLG ...
Error: unable to perform an operation on node 'rabbit@DESKTOP-8VB0JLG'. 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-8VB0JLG
