I have two microservices apliations say App1 and App2 hosted on an IIS server. I am using IDistributedEventBus (https://docs.abp.io/en/abp/latest/Distributed-Event-Bus) to Publish event that contains only a GUID property. App1 successfully publishes the event and the message getting added to Queue in RabbitMQ. But the HandleEventAsync method of IDistributedEventHandler in App2 is not being called even if the App2 is in always running mode. Sometimes, HandleEventAsync gets called when we explicitly call an API of App2.
What can be the issue? Am I missing something?
