About access unstract web from other computer

It seems the webUI can only access through http://frontend.unstract.localhost/ which point to 127.0.0.1

I'm trying to setup nginx to reverse proxy to it through another URL and set host header to frontend.unstract.localhost. Can see the login screen but will redirect back to http://frontend.unstract.localhost/!!!

Is there anyway to setup with another hostname? Please advise?

Thanks, Halu
