Error message

no config files found at %s

What it means

Error from config.C.Load: the resolve pass over the configured path found zero YAML files. The path exists (or stat failed silently) but no loadable YAML was discovered, so there is nothing to parse; the path itself is included in the message.

Solutions

1. Point -config at a directory containing .yaml/.yml files or at a single YAML file
2. Check the filename extension matches what the loader accepts
3. Verify the path was not mistyped
