Port forwarding stoped working

I ran a Minecraft server on my computer and it ran fine. That was about a year ago. Now when trying to run a Unturned server with the port 27015, it doesn’t work, nor doesn’t it work for Minecraft. Weirdly enough, the original server port forward had no device assigned to it. Is there anything I can do to fix this? I believe the issue lies in my device as port forwarding works for everything else. Did a windows update or factory reset mess it up? What changes that might have occurred should I reverse?
