❌ ~ getRepayByMessage ~ e.message: 14 UNAVAILABLE: No connection established. Last error: Client network socket disconnected before secure TLS connection was established (2024-05-20T12:11:41.245Z)
```

Start with the loopclient service in docker.compose.yml and the JavaScript SwapClient setup that calls getInfo. Check the container's exposed 11010 endpoint, TLS certificate paths, and client connection settings, then reproduce the call and use the loopclient logs to identify why the TLS connection is not established. Done means the regtest getInfo call connects successfully and returns a response.
