i am facing a strange problem in my AWS setup at the moment.
I am running a Openldap Multi Master Cluster on AWS with 2 instances present. Those 2 instances are behind an AWS Applicaiton Loadbalancer with Port 389 Open to both instances. LDAP works without any fault but when i try to SSH into one of the 2 instances (via instance ip not via Loadbalancer DNS!) i get a timeout.
Now up to the strange part. When i remove any of the instances from the loadbalancer i can ssh again.
Logs aren't helping at all and i never faced such a problem with instances inside our other loadbalancers.
Anyone faced a similar problem maybe suggest a solution?
