Configure your Minecraft server by following the setup steps carefully.
Configure your Minecraft server by following the setup steps carefully.
I and my friends were feeling bored, so we set up a MC server just for fun. But somehow neither of us managed to get it running on our machines. Anyone can help us figure out what went wrong? We've tried: checking for typos in port forwarding, letting it through the firewall on the PC and modem, turning off the firewall, using both IPv4 and IPv6, changing ports (like not 25565), disabling and removing antivirus, letting others host it, and setting a static local IP in the adapter. We've watched lots of tutorials, but it still doesn't work. I'm ready to share any screenshots you need so we can see where we went wrong. Also, we think our ISP (Xfinity) might be the problem, but we haven't found anyone else with the same issue online. Please let me know if this helps. Thanks!

ORT format (e.g., 123.123.123.123:25565). If using the same client as your play device, you're likely misconfiguring. This is not a Realm; skip any skipped steps. If problems persist, troubleshoot further.

Ensure your own server can be joined first; local joining usually succeeds. Remove Avast if you encounter issues. Most connection problems reported are due to Avast interference. Begin with the default port (25565), or try 22 for SSH, which should work regardless of ISP. Run CMD and type "ipconfig" to view your IP address. Use this address in the next step. Trace the entire network path from the wall to your PC, following each link sequentially. For example, if using a modem and router, route through the modem to the router, then to the PC. If a switch is involved, consider bypassing it temporarily. Ensure no device is forwarding the same IP address, as this may indicate misconfiguration. Verify your Minecraft version matches what you plan to host. Only run the server using the correct Java Edition settings—IPORT format (e.g., 123.123.123.123:25565). If using the same client as your play device, you're likely misconfiguring. This is not a Realm; skip any skipped steps. If problems persist, troubleshoot further.

05-21-2016, 10:23 PM #5I faced an issue with my server. Fortunately, my brother works in IT. In short, my ISP was assigning me a dynamic IP address. This usually prevents hosting anything on the network, especially public services. If that’s the situation, you might need to upgrade your internet plan for a static IP or ask someone with a fixed IP to host it.
Dynamic IP refers to the possibility of changing address, often after rebooting networking equipment. It’s unrelated to hosting servers; with dynamic IP you only need to pass along the updated address to others. A domain makes this process smoother and more convenient. Check your sources before disputing, as your sibling might have overlooked the real problem.
Thanks for the suggestions. I’m able to connect to the server by entering my external IP address, but none of my friends can join when they try. I’ve checked port checkers and it says the port isn’t open. I’m wondering if this is the issue: when logging into my router, it shows no IPv4 address. While searching for my IP on Google gives me IPv6, some sites show IPv4 addresses. Could this be the problem?
Here’s a clearer version of your message:

05-28-2016, 05:12 PM #8The system you're referring to handles port forwarding. I'm new to IPv6 but can forward the IPv4 address shown in the "ipconfig" command on the host machine. Use port 25565 and test both TCP and UDP protocols. They'll need the external IP to connect.
As long as the 192.168.0.30 IP comes from the same machine running the server, it should function. You shouldn't need to but consider adding 25565 to the address shared with friends. The format should be "xxx.xx.xx.xxx:25565". Ensure the server.properties file has the port set to 25565.
