Getting a 400 Bad Request when hitting the min.io browser login

I've configured a monitor to check out Minio instance. The section of the heartbeat.yml is below (address and credentials replaced with "x"s).

I can log into the site using the credentials with a browser and I have double checked the URL, etc.

Any help is appreciated!

Unfortunately a 400 error isn't much info. Are you sure that minio uses HTTP basic auth? It looks like you're pointed at a login page, which hints to me that it may uses a custom auth scheme.

Thanks for the quick response. I did some more research and discovered it does not use basic authentication, but rather AWS Signature Version 4. Is it possible to set that in the monitor configuration?
