Getting 509 error from RabbitMQ

[shahar-kela]

I have an *.my-domain.private ca/intermidiate.crt.pem, server/star.my-domain.private.key.pem and server/star.my-domain.private.crt.pem.
On the secret I put the intermidiate on ca
cert is server/star.my-domain.private.crt.pem and key is server/star.my-domain.private.key.pem
host is amqps://user:[email protected]:5671/
and this is my keda details

Not sure why the keda-operator on namespace keda return error 509
