Replying to my previous comment -
Turns out my server is displaying on the server list however, i suspect due to it being forced through a VPN tunnel via my router Plutonium is displaying the VPN's IP opposed to my at-home IP, this is likely preventing people from connecting through the server browser.
i figured this out when i checked out https:// pluservers.ddns .net/ (i cannot post links here, hence the spaces) and was able to see my server there with the VPN's IP.
Unfortunately my other machine, that isn't behind a VPN and is exposed to the internet via port-forwarding, has an Arm chipset and currently will not work with the container images that i currently use.
