I can't access my HA after new installation on my Ubuntu server [VM][KVM]

Hi use ubuntu server and i have create VM with HAOS.
Installation it good but i cant connect to HA in a web browser.
I newbie with linux server and also.
I use tailscale to access all my other services using port.
I have try to enter my VM ip into my browser but it not working.
Can someone help with that?
How can I set up my virtual machine to be accessible from my tailscale like this → myTailsclaeIP:8123.
Thank you in advance.

This is a new installation, so drop the :8123. New installs use the default port (:80) so you don’t have to specify it.
