mc admin service status sia

returns

The server is offline.

While the server is running and the gui is running fine?

For a local minio server:

mc admin service status local
Uptime: 2 hours 49 minutes 10 seconds

Add a host to mc

mc config host add sia http://192.168.1.x:9000 AccessKey SecretKey

All looks well in the log:
