Cannot connect after a fresh install on Windows

[Hrusikesh Panda]

I never had any prior versions of Erlang VM or RabbitMQ Server. This is a completely fresh install.

What I did:

• Downloaded and installed otp_win64_18.2.1.exe
• Downloaded and installed rabbitmq-server-3.6.0.exe
• The Rabbit MQ Service is started and running
• ERLANG_HOME variable is set 
• Allowed Windows Firewall All ports, inbound full access

So everything went fine it seems. However, 

• I cannot connect to web interface: http://localhost:15672/ -> gives me "localhost refused to connect."
• I created the Hello World Tutorial (https://www.rabbitmq.com/tutorials/tutorial-one-dotnet.html) using RabbitMQ.Client v3.6.0 NuGet package
• When I run the sender or receiver, I get: 

Exception information: 
    Exception type: ConnectFailureException 
    Exception message: Connection failed
   at RabbitMQ.Client.Impl.SocketFrameHandler.Connect(ITcpClient socket, AmqpTcpEndpoint endpoint, Int32 timeout)

   at RabbitMQ.Client.TcpClientAdapter.EndConnect(IAsyncResult asyncResult)
   at RabbitMQ.Client.Impl.SocketFrameHandler.Connect(ITcpClient socket, AmqpTcpEndpoint endpoint, Int32 timeout)

I'm not sure what I'm missing.

I'm running Windows 7 x64 with SP1.

Also note that logs folder is completely empty %APPDATA%\RabbitMQ\log

Have you installed raabitmq management plugin? I suppose it is required to access web interface.

Whi ch either means that RabbitMQ logs elsewhere or that the node was never started.

Thanks Ashutosh, Michael for your replies.

The management interface works if I run the server as a console app via rabbitmq-server.bat

I see the RabbitMQ service running, so will that not suffice? I was assuming that will run the broker as Windows service and thus the console app will not be needed.

How do you check that it is running?

What does `rabbitmqctl.bat status` output?

[Hrusikesh Panda]

services.msc shows its running. 

`rabbitmqctl.bat status` shows this:

That means RabbitMQ is not running.

First things to check would be http://www.rabbitmq.com/windows-quirks.html. 

[Hrusikesh Panda]

Already checked the quirks page. I don't see any of those problems.

If we don't have any RabbitMQ logs, then some kind of Windows event or service log may
have a clue. 

[Hrusikesh Panda]

Windows Event log doesn't have anything. And logs directory is empty. So are there any other places I should be looking at?

Or maybe I should try to magic bullet solution to all windows problems - reboot the box! :)

also, you can try re-installing the service via `rabbitmqctl.bat`, as mentioned on
http://www.rabbitmq.com/configure.html

I'm not a Windows expert. Try re-installing the service and running `rabbitmq-server.bat` in a
console, perhaps that will  report something.

[Hrusikesh Panda]

Uninstall/reinstall seems to have made some progress but not much:

I synced the cookie manually but don't know what to do about the other 2 suggestions. I know there are config options to handle those, but shouldn't the defaults cover this simple scenario?

The suggestions are alternatives. It's the cookie location that's incorrect 99% of the time.
`rabbitmq-plugins` uses the same authentication mechanism, so it needs to be fixed
even if you don't touch rabbitmqctl for a  while.
