Can't connect to event hub from external machine. Connection setup timeout

Hi, I have a Apachel Camel application with a route to produce and another route to consume from Event Hub.

I'm using kafka connector and it was working fine. Recently new servers were created but I can't make it work on new servers.

We get the following error on startup:

[] 2024-02-23 16:16:50,683 WARN org.apache.kafka.clients.NetworkClient$DefaultMetadataUpdater: [Producer clientId=producer-1] Bootstrap broker bbnmsls-cim-ml-st-evhns.servicebus.windows.net:9093 (id: -1 rack: null) disconnected [] 2024-02-23 16:17:02,888 INFO org.apache.kafka.clients.NetworkClient: [Producer clientId=producer-3] Disconnecting from node -1 due to socket connection setup timeout. The timeout value is 24155 ms.

And this error when app try to produce:

org.apache.kafka.common.errors.TimeoutException: Topic bbnmsls-cim-ml-tmf-nc-evh-test not present in metadata after 60000 ms. > [] 2024-02-23 14:41:25,909 WARN org.apache.camel.spi.CamelLogger: Execution of JMS message listener failed. Caused by: [org.apache.camel.RuntimeCamelException - org.apache.kafka.common.errors.> TimeoutException: Topic bbnmsls-cim-ml-tmf-nc-evh-test not present in metadata after 60000 ms.] org.apache.camel.RuntimeCamelException: org.apache.kafka.common.errors.TimeoutException: Topic bbnmsls-cim-ml-tmf-nc-evh-test not present in metadata after 60000 ms.

Server, topic and authentication properties are correct. We also tried telnet to host and port and it is working fine. Any suggestion or comment will be appreciated.
