Hint for HELP

Got user, found creds for (I ASSUME based on the context) the service on port 3***. when I try to access M****** via command line, I get an error “Host Unreachable.” Host is definitely reachable (I can still hit it in the browser), so I’m confused what else might be causing that error. Google hasn’t been very helpful.

Am I barking up the wrong tree with M******? Is there a flag/option I should be specifying? Is this possibly caused by another user borking the machine, and I should reset?
