Service Unavailable error while sending mqtt message on solace


I created a new message VPN on solace VMR and configured its SSL port as 8884 . Configured default ACL profile on it to allow publish and subscribe both . But when I am trying to publish any message on a topic such as "hellotopic" , I am getting an exception like :

Exception occoured Client is currently disconnecting (32102)
Connection lost on instance "123456" with cause "Connection lost" Reason code 32109" Cause "java.io.EOFException"

While in solace VMR event logs , It gets connect and disconnects instantly: -

Tried to find solution of this , Got some information regarding I am not authorized to publish on following topic.

P.S. - I am able to publish messages on default VPN SSL port.


Solution

  • You said that you can publish messages at QoS 0 and not 1: did you configure a Spool size at your message VPN? You may want to have a look at the Product Documentation at (step 17) and add a size to the Maximum Spool Usage property:

    Maximum Spool Usage

    The maximum amount of message spool disk space (in MB) the Message VPN may use. Note: No policing is done to ensure that the sum of all of the message spool quota allocated to Message VPNs does not exceed the router-wide message spool quota.

    By default, the value of this property is set to 0, you may try and set it to 5 or 10 (in MB).
