So me and two friends wanted to play Minecraft again. I created a server via my WLAN router, so I activated UCP and TCP there. I gave them my IP and they could join without any problems. And today they can no longer join. I checked if my IP changed but it didn't. Then I restarted my router and gave them the new IP. A friend was not there yet, but I was able to join the other with no problem. When the other came, the server could not be found. Then I restarted the server and both of them couldn't do it again…
What IP address did you give them? One with 192.168.x.x / 10.x.x.x at the beginning?
What is the network structure like?
Which provider? We need a lot more information ;-)
Which router do you have?
My IPv4 which I get at wieistmeineip.de. Provide is Telekom. What do you mean by building a network?
Speedport 3 from Telekom, but as I said, sometimes we can all join and then sometimes not.
Buy a fritzbox.
Ah yes
Is meant seriously. With speedport you only have theater as you see yourself now. Last year, a doctor's office routed patient data open to the network due to a bug in the activation in Telekom
