UID & GID variables not set & localhost:3080 not resolving

[ByJovey]

Hi there

New to playing in the LibreChat space.

Decided to install (locally) over Ubuntu LTS 24.04. And Ubuntu is installed within Virtual Box 7.1.6, which is over Windows 10 (OS Patches all up to date). The metal is a Lenovo ThinkPad X1 Carbon 6th edition.

I followed the steps in this video: https://www.youtube.com/watch?v=w7VqivpdfZk
Here are the steps:--
Update the system: sudo apt update
Clone LibreChat: git clone https://github.com/danny-avila/LibreC...
Install Docker: sudo apt install docker.io && apt install docker-compose -y
Enter the folder: cd LibreChat
Create the .env file: cp .env.example .env
Build the Docker image: docker-compose build
Start LibreChat: docker-compose up -d

Quite of few of the above steps needed troubleshooting to resolve one thing and sometimes another.

And after some troubleshooting, got through the last step:-- docker-compose up -d

However; when running the last step, the following:--
'WARNING: The UID variable is not set. Defaulting to a blank string.
WARNING: The GID variable is not set. Defaulting to a blank string.'

Should I be concerned about those warnings?
Do they matter?
If they do; seeking solution guidance!

And; after bringing Docker Compose up, I also attempted to resolve through Firefox browser, within Ubuntu, localhost:3080 -- would not resolve. I also attempted with 172.104.247.225:3080 -- also would not resolve. I then attempted the same from a Firefox browser on my host Windows 10 system -- neither also would not resolve. Within Ubuntu, I also allowed port 3080 through an associated firewall setting. Still would not resolve within Firefox from within Ubuntu. General web surfing is working fine -- eg Google searching and so forth.

Seeking your help / guidance re the above.

Regards
