I set up a Minecraft server on a separate computer from the one I'm trying to connect to. It's running on an Ubuntu server with PufferPanel installed too. I have the server port forward to 25567 on TCP AND UDP and I have set up a DHCP IP reservation. The server seems to run fine in the console however I am unable to connect to it even on the local network. I have tried connecting with the device running the server's IP address and my external IP address and I have specified the port by following the IP address with :25567.
