Unable to connect to OE Management

Hi,

Installed evaluation v12's OE Management on a virtual CentOS box. Everything default, no changes. proadsv and fathom has already been started.

But when I try to curl http://localhost:9090 , no response. However, localhost-access log writes something like this. 

    24/May/2019:11:32:07 -0700 "GET / HTTP/1.1" 302 - 2 catalina-exec-6

What could be wrong in my setup?

(Trying to use curl, because Windows host receives Network Error, added exceptions to the firewall already)

TIA!
