not able to scan kafka topics

[ak1att]

I am exploring this tool , I got my topics created, Also I am running my producer app to publish events continuously and expecting when I run http://localhost:8120/#/kafka-plugin with all required information I should be able to reverse engineer events to generate AsyncAPI but after multiple retries ends up in this error. My java consumer works good and I can see my events, Here is error snippet
2022-10-05 17:52:00.462 WARN [] 42308 --- [ce_admin_client] org.apache.kafka.clients.NetworkClient : [AdminClient clientId=solace_admin_client] Connection to node -1 (zlty10431.vci.att.com/135.150.110.16:2024) terminated during authentication. This may happen due to any of the following reasons: (1) Authentication failed due to invalid credentials with brokers older than 1.0.0, (2) Firewall blocking Kafka TLS traffic (eg it may only allow HTTPS traffic), (3) Transient network issue.
