Hi there Didier / @coz787 , welcome to the Community!
Ok, so the Solace broker is complaining about something in the AMQP exchange, but not sure what. Solace QA used other QPid APIs to test our AMQP interoperability, so hopefully this is something that we can resolve.
Is it possible for you to take a packet capture from your client-side? There are more details about the error emitted by the Solace broker, but these are not exposed in the QPid client. You’d be looking for an info map inside the error.
It’s been a while since I’ve used WireShark, but there’s an AMQP display filter which should help! https://wiki.wireshark.org/AMQP.md Keep us posted if you can get a packet capture.
