Vault agent injector failing

Vault
1

I am trying to create vault agent injector to external vault service which is deployed on OCI. I am trying to create a vault agnet injector in my deployment and seeing errors in pod logs as pod is not coming up.

2022-02-01T22:12:53.205Z [ERROR] auth.handler: error authenticating: error=“context deadline exceeded” backoff=1s
2022-02-01T22:12:54.205Z [INFO] auth.handler: authenticating

Below is my deployment yaml file.
