I can SSH to VM but can't open server content from browser from another PC on the LAN

I have Ubuntu 20.04 VM on Windows 11 host. The network is NAT

Windows 11 host IP = 192.168.10.25

VM IP = 10.0.2.25

ufw is inactive

NAT ports forwarding rules on VirtualBox:

Rule #1: SSH
Protocol: TCP
Host IP: 0.0.0.0
Host Port: 22
Guest IP: 10.0.2.25
Guest Port: 22
-------------
Rule #2: HTTP
Protocol: TCP
Host IP: 0.0.0.0
Host Port: 80
Guest IP: 10.0.2.25
Guest Port: 8000

I have all ports open in the Windows 11 host firewall outbound and inbound rules.

From PC2 (a PC on the LAN), I am able to SSH to the VM with PuTTY using 192.168.10.25@22

Then I start the server on port 8000 on the VM, and it shows: Development server started on 127.0.0.1:8000

Then I go to the browser on 192.168.10.25 (no port because I forward 80 to 8000), but I get "Site can't be reached".

Then I try to SSH from VSCode terminal and start the server again, and then VScode pops up a message saying "port 8000 forwarded automatically", and then I go to the browser on 127.0.0.1:8000 and it shows me the website.

How come it let's me see the website from PC2 which is separate from the host/VM and see it on its own loopback IP 127.0.0.1:8000? And how to make it work from the correct IP?

I sit in a Tesla and translated this thread with Ai:

EN: I can SSH to VM but can't open server content from browser from another PC on the LAN

TH: ฉันสามารถ SSH เป็น VM แต่ไม่สามารถเปิดเนื้อหาเซิร์ฟเวอร์จากเบราว์เซอร์จากพีซีเครื่องอื่นบน LAN

RO: Pot SSH la VM, dar nu pot deschide conținutul serverului din browser de pe un alt PC pe LAN

RU: Я могу использовать SSH для подключения к виртуальной машине, но не могу открыть содержимое сервера из браузера с другого компьютера в локальной сети.

VI: Tôi có thể SSH tới VM nhưng không thể mở nội dung máy chủ từ trình duyệt từ một PC khác trong mạng LAN

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
