Refer to RabbitMQ's Connections documentation (opens in a new tab) for more information about the service.

Using user connection

To configure this credential, you'll need to have a RabbitMQ broker (opens in a new tab) installed and:

1. Enter the Hostname for the RabbitMQ broker.
2. Enter the Port the connection should use.
3. Enter a User the connection should use to log in as.
   • The default is guest. RabbitMQ recommends using a different user in production environments. Refer to Access Control | The Basics (opens in a new tab) for more information. If you're using the guest account with a non-localhost connection, refer to guest user issues below for troubleshooting tips.
4. Enter the user's Password.
   • The default password for the guest user is guest.
5. Enter the virtual host (opens in a new tab) the connection should use as the Vhost. The default virtual host is /.
6. Select whether the connection should use SSL. If turned on, also set:
   • Passwordless: Select whether the SSL certificate connection users SASL mechanism EXTERNAL (turned off) or doesn't use a password (turned on). If turned on, you'll also need to enter:
     • The Client Certificate: Paste the text of the SSL client certificate to use.
     • The Client Key: Paste the SSL client key to use.
     • The Passphrase: Paste the SSL passphrase to use.
   • CA Certificates: Paste the text of the SSL CA certificates to use.

guest user issues

If you use the guest user for the credential and you try to access a remote host, you may see a connection error. The RabbitMQ logs show an error like this:

[error] <0.918.0> PLAIN login refused: user 'guest' can only connect via localhost

This happens because RabbitMQ prohibits the default guest user from connecting from remote hosts. It can only connect over the localhost.

To resolve this error, you can:

• Update the guest user to allow it remote host access.
• Create or use a different user to connect to the remote host. The guest user is the only user limited by default.

Refer to "guest" user can only connect from localhost (opens in a new tab) for more information.
