Hi @gowthamr-TU ,

I don't have much experiance with AWS, but the error message is quite straightforward. Check your inbound rules of the Network ACL (acl-0e9b635f05cdd3f9a) associated with the subnets. It looks like this ACL is blocking inbound traffic that is required by Databricks workspace. 
Databricks requires subnet-level network ACLs to add 0.0.0.0/0 to your allow list.
