I've been connecting to Google Cloud SQL Postgres Instance from the CloudSQL Proxy on Windows for years. All of a sudden, I'm unable to connect

When I start the proxy using Cloud SDK, it launches fine and says ready for new connections. Then when I try to connect to it on 127.0.0.1, the client throws error : couldn't connect to "instance": tls: server selected unsupported protocol version 303

My cloud run service is able to connect and even I am able to connect using cloud shell. I am facing this issue only while trying to connect using cloud sql proxy.

Any thoughts on this issue is much appreciated.
