Can you check the security group configuration on the security group used to launch the DAX cluster? You will need to authorize inbound traffic on TCP port 8111 on the security group used to launch the cluster, using the security group used for the lambda function configuration as the source. Please refer to the documentation for more help.

This is connection time out Exception. you should check AWS firewall settings if port 8111 is open in inbound rules.

These settings are on AWS dashboard in security policy section.
