JustKir 0 Posted June 5, 2021 I am trying to port forward my router so my friends can join my minecraft server, It is needed for TCP & UDP to be port forwarded but UDP always leads to "Duplicated Port number" error. TCP port forwarding worked, but UDP just doesn't. The port needs to be 25565 for the minecraft server to work. Please help me I have been trying all day and troubleshooting but haven't found a way to get my friends to connect to my Minecraft server. Quote Share this post Link to post Share on other sites

If it is claiming as a duplicate port, some other program on another device on the network is using it. Change the port. Quote Share this post Link to post Share on other sites
JustKir 0 Posted June 5, 2021 I have already tried that, and I tried many random numbers but UDP wouldn't work, also no other devices on the network are using that same port as I checked multiple times over. I know what the duplicated port error is, I just don't see the problem anywhere, therefore I can't fix it. TCP works, UDP doesn't. No idea where's the problem since I've been looking around and researching for hours. Quote Share this post Link to post Share on other sites
