Data is not being replicated between patroni postgresql nodes

Question

Issue: Data is not being replicated between nodes. Postgres version: 14 I have set up patroni server with one leader and three replicas with HA proxy as load balancer. Automatic failover is working fine, when a leader is down patroni will bring up replica node as leader.

Below is the output when I list patroni cluster:

+ Cluster: postgres (7322782945008862801) ------+----+-----------+
| Member | Host               | Role     | State      | TL | Lag in MB |
+--------+----------------+---------+-----------+----+-----------+
| node1  | 10.113.123.155 | Leader  | running   |  1 |             |
| node2  | 10.113.123.156 | Replica | streaming |  1 |         0 |
| node3  | 10.113.123.157 | Replica | streaming |  1 |         0 |
| node4  | 10.113.123.158 | Replica | streaming |  1 |         0 |
