For using rabbit mq on windows 10 for similar error I did below

  1. set RABBITMQ_NODENAME=rabbit@localhost in the path where rabbit MQ is installed i.e for me it was in C:\Program Files\RabbitMQ Server\rabbitmq_server-3.8.5\sbin> and then started .\rabbitmq-server start

Also, I had changed the host to point to my computer name in c:\Windows\System32\Drivers\etc 127.0.0.1 yourhostnamehere

Or, edits your hosts file so that INLN50899724A points to 127.0.0.1

Remove the RabbitMQ service. Uninstall RabbitMQ. Kill the epmd.exe process. Delete your c:\users\\AppData\Roaming\RabbitMQ Directory.

Go to Control Panels -> System -> Advanced -> Environment Variables

Add a variable named RABBITMQ_NODENAME and set it to rabbit@localhost

Reinstall RabbitMQ.

Navigate to the RabbitMQ sbin directory (or run the command from the start menu) and run rabbitmqctl status.

You should no longer see the (cannot connect to host/port) error.

And yes, this will fix your Cisco AnyConnect VPN related installation issues.

For Windows Machine:

  • Go in C:\Users\<YourUserName>\AppData\Roaming\RabbitMQ
  • Create a file rabbitmq-env.conf

  • Add the following:

    CONFIG_FILE=C:\Users\<YourUserName>\AppData\Roaming\RabbitMQ\rabbitmq
NODE_IP_ADDRESS=127.0.0.1
NODENAME=rabbit@localhost

  • The above is my env-config, for this particular issue setting the nodename will be sufficient.

  • Turn off you firewall & start the rabbitmq, it will work. After running it one time, even if you turn on the firewall, it will work.

This works for me in Windows 10 machine.

I may be replying really late, but still I'm facing this issue. So it may help somebody event while installing rabbitmq version 3.6.5. To change the node name, open "rabbitmq-env.bat" under "installation dir\sbin" and change RABBITMQ_NODENAME to "rabbit@localhost" (line number 90 in rabbitmq 3.6.5). But make sure you remove the windows service, do change the nodename, install service and start it. This worked for me. No other options worked for me which were marked as right answer in stackoverflow!
