failed loading configuration file at [%s]

Error message

failed loading configuration file at [%s]

What it means

getMspConfig: the MSP config.yaml exists (os.Stat succeeded) but reading it failed (permissions, truncation, I/O error). The %s names the config file path; contrast with the silent skip when the file does not exist.

Solutions

1. Check file permissions and readability of the config.yaml
2. Restore the file if truncated or corrupted
3. Verify the path points to a regular file
