Hello Balena fam,
So i’ve been trying to get this working for a month now, and although i’ve gained a lot of ground, i am stuck at the final most crucial bit.
Im running a ubuntu VM inside a libvirt stack ubuntu container.
when trying to access port 80 inside the ubuntu container, I can successfully see the webpage via the public URL, using a quick python webserver to test.
if i run the python webserver test inside the VM, I can successfully curl that URL via the container, but I cannot see the content on the public URL.

Can someone please help me understand where I’m going wrong.
The container is running with network:bridge enabled.
Any help would be greatly appreciated.
Kindly,
Puc
ps. willing to change up anything, and ideally keep things as minimal as possible, but i’ve just tried so many different things.
