I’m trying to start a new cluster named pxc-cluster  
Cluster is being bootstrapped successfully but galera library isn’t being read if placed in wsrep.cnf but after transferring it to my.cnf it shows the following error:

Hello Aldrin and Welcome to the Percona Community.

So, reading error log whenever I see “Connection timed out”, I always question that something is blocking me from talking to someone else on the other side. Check firewalls selinux or other networking access and verify that the following ports are open: 3306, 4444, and 4567.

Also [check this question](https://forums.percona.com/t/getting-error-after-configuration-percona-xtradb-8-0/7894/13) hinting at similar problems for PXC.

Thanks,  
Kedar.

Thanks for the reply @kedarpercona, those ports were already added to the security group of both ec2-instances. Anyways we found out that the config file location was the issue. We transferred the config from wsrep.cnf to my.cnf.
