Instances not communicating across Availability Zones within a single region

I have the following instances, they are in the same VPC and region but different AZs, both of them are in the same SecurityGroup.

Subnets:

These two instances are not able to communicate with each other. What do I need to do to enable communication between these two AZs?

Here is the main route: enter image description here

Subnet 1: Subnet 1

Subnet 2: Subnet 2

You have to open the needed ports in the SecurityGroups of the EC2s. You should also look into your subnets and the routing tables of these subnets or your VPC.
