Made sure my pc had Network discovery on. Checked the router, upnp is enabled. Tried port forwarding with setting my device and local port start and ends at 42420 with WAN ports the same. Tried DMZ hosting to put my pc outside the routers firewall and everytime i go to try to open my singleplayer game to the internet it tells me "no upnp or nat-pmp device found. Please make sure your router has upnp enabled" What am i doing wrong?
