Host PC fails to access Webmin which is installed on CentOS in VirtualBox

Webmin can be accessed over SSH after forwarding the port. Now I am trying to access Webmin's control panel on my computer outside virtualbox but on the same computer, but it doesn't load. I tried using the same port forwarding settings as is working fine for SSH, for both port 80 and port 10000, but it still doesn't load. The browser error says, This site can’t be reached The connection was reset. Here's my network settings for port forwarding in virtualbox: Steps to reproduce: 1. Install fresh CentOS 7 x64 (latest) 2. Install Webmin 3. yum update -y 4. Add Port Forwarding rule for 2222 to 22 to make SSH work 5. No iptables are installed. Just vanilla CentOS 7 x64 latest with Webmin latest freshly installed. 6. Open browser on computer (the same computer running VirtualBox & SSH but outside VirtualBox), and go to http://127.0.0.1:10000 It fails to connect. This is what I want to see (pulled screenshot from the internet): I also tried accessing from 192.168.x.x (my PC's IP), but I get connection refused: I tried forwarding port 10000 to my local pc's IP port 10000 too, but still doesn't work: I can't use bridged because port forwarding is greyed out. I did try setting up a bridged connection, but then even SSH wouldn't connect, as well as either my host PC's IP (http://192.168.x.x:10000 ) or (http://127.0.0.1:10000 ) To troubleshoot I ran nmap in SSH: # nmap 192.168.x.x -p 10000 -sU -sT -Pn --reason Starting Nmap 6.40 ( http://nmap.org ) at 2022-06-14 21:33 EDT Nmap scan report for DESKTOP-CHTUIRP (192.168.x.x) Host is up, received user-set (0.0013s latency).
