AMP Not working - "Welcome to NGINX"

Ubuntu 24.04:

Not sure of the AMP version because i cant access the panel.

Problem Description:
i am unable to access to my amp instance. Im not sure when it happend, was working 2 days ago. I have not done anything with my router setup, or my server.

Steps to reproduce:

• Reboot
