+## AWS MSK: TimeoutException
+
+Thanks to ahlooli#2666 on discord:
+
+1. Create a secret in AWS secret manager store that contains key:value pair with 1 username and 1 password, there are certain rules to be followed like the name of the secret (eg. need to start with MSK\_ \*\*), so need to refer back to AWS documentation.
+2. Proceed to MSK console and create the MSK cluster, my cluster was the "provisioned" type. Then choose SASL/SCRAM. Another option also needs to follow documentation for your preferred configuration.
+3. After the Cluster has been created, you can then proceed to associate the Secrets created earlier to MSK cluster. (Done in MSK Console)
+4. Then we can proceed to create a custom security group that allows port 9096 (or whichever MSK broker is using). Rough idea:
+   1. Source: ESK cluster security group
+   2. Type: TCP
+   3. Port: 9096
+5. Find out all the MSK's broker ENI. Proceed to attach the above sec. group to each ENI. (if you have 3 brokers which means you have 3 Eni, you need to do it manually 1 by 1)
+
+At this stage, the AWS side should have sufficient permission to allow KAFKA-UI to communicate with it.
