VPS [Ubuntu] > Docker > Apache (serving Oracle APEX)

So locally I run Ubuntu on my laptop. I have followed the instructions provided to me by an author on Github to install docker and subsequent software (Oracle DB 19.x, Oracle ORDS, Oracle APEX, Apache, to name a few).

When I've done this locally, I was able to access APEX via:
localhost:8080/ords/

I have followed the exact steps on my Ubuntu VPS within Linode, I can SSH into the docker container and access the Oracle DB SQL cl in my terminal, plus I can within TOAD, access the db directly calling my VPS IP address using port 1521, and interact with the DB just fine.

I have been all over trying to acccess APEX from my browser [VPS IP]:8080/ords/ and have no luck.

By all accounts all is there and working, but no matter what I am having no success.

When implementing the container, I ran:
docker run -d --name db-apex-dev-container -p 2222:22 -p 8080:8080 -p 1521:1521 -v /dev/shm --tmpfs /dev/shm:rw,nosuid,nodev,exec,size=2g db-apex-dev-image

I have also pared that back and just tried to expose 8080, still nothing.

Can anyone help me gain access via my local browser to the Apache instance within docker?

I provide the output of netstat -plunt and iptables-save in the first comment.

Adding this to help someone else who may understand this better than me:

I had attempted to utilize UFW however I later found that by default Docker writes directly to IPTABLES. I have since reset UFW and it's currently inactive as of running these 2 commands:
