Not able to connect to AWS RDS postgres DB

Hello All, I am using istio 1.15.3 when I am trying to communicate to AWS RDS postgres DB when the istio is injected, I am getting authorization issue with password. But when I disable the injection of istio I am able to make a communication.

Any one face this issue

It is quite generic and hard to figure out what is the exact issue.
You may need to double-check the credential and the security group of RDS.
If you wanna discuss more, please attach some screenshots or error message, so we have better understanding about your issue.

Thanks,
Trung.

The connection is happening but, when I login to the pod and try to login to the DB it is throwing the credential are wrong
