Describe the bug
I used the example docker compose to write my own stack, with a cloudflare tunnel, some bind mounts, and internal network that will be for adding containers to. However, after deploying my compose, I was not able to access the panel at http://<your_server_ip>:8080/install, making me unable to set up my instance.

To Reproduce
Steps to reproduce the behavior:

Deploy docker compose
Navigate to http://<your_server_ip>:8080/install
Get 'Unable to Connect' error

Expected behavior
I should be able to access the container at the URL in the docs

Info (please complete the following information):

Server OS: TrueNAS Scale 25.10.1 (kernel 6.12.33)
Server Arch: x86_64
Nginx UI Version: 2.3.2
Your Browser: Firefox

Additional context
I ended up binding 9000:9000 and being able to set it up there, but only after I did a combination of clearing my bind mount directories, setting NGINX_UI_IGNORE_DOCKER_SOCKET=true with the guidance of DeepWiki (I don't know if this helped), and waaaay more research than it should have taken.

Here is my docker compose for reference

compose.yaml

I only changed my port mappings to 80:80 443:443 after I gained access to the Nginx UI panel.

  cloudflared:
    image: cloudflare/cloudflared
