Error when following MSK documents

Question

Hi I was trying to follow the document in creating a MSK for project use (https://docs.aws.amazon.com/msk/latest/developerguide/create-topic.html ). I followed the steps until step 3 and received the following error message. Just wondering if there is an account-specific issue, or if there is an updated document to follow.

"Error while executing topic command : Call(callName=createTopics, deadlineMs=1674775795279, tries=1, nextAllowedTryMs=1674775795380) timed out at 1674775795280 after 1 attempt(s)

Answer

In most cases, TimeoutException is coming due to the incorrect properties for the selected protocol, or network-security configuration.

Steps for troubleshooting:
1. Telnet to the port you are using in bootstrap string (it should be one of 9092, 9094, 9096 or 9098 depending on which authentication mechanism you are using): `telnet  `
    a. if you cannot connect, check Security Group settings (step 2:  items 9-14)
2. If telnet works, check that you have correct properties for the selected authentication mechanism. Ref: https://docs.aws.amazon.com/msk/latest/developerguide/iam-access-control.html

If still doesn't work, please add a comment with: exact command you are executing (replace only host name with a token, but keep a port).
if a port is not 9092, please provide a content of property file which you add as a command-config to your command. Please replace any sensitive data (credentials, role names, etc) with tokens.
