Overview

The purpose of this page is to list troubleshooting guides and work-arounds for issues that you may run into when using the Coherence Go Client. This page will be updated and maintained over time to include common issues we see from customers.

Receiving "first record does not look like a TLS handshake"

Problem

You receive the following error trying to create a session using coherence.NewSession:

code = Unavailable desc = connection error: desc = "transport: authentication handshake failed: 
    tls: first record does not look like a TLS handshake"

Solution

You are trying to connect to a non TLS enabled gRPC Proxy using TLS. You should either specify coherence.WithPlainText() or correctly enable TLS. See NewSession for more information.
