I created a server for the modpack "Forever Stranded" on my own PC. So that friends can also join the server, I have defined a port in the server config and released it in the Fritzbox (TCP). I myself can join via localhost: [Port], however neither I nor others can join via [IP]: [Port] and I get the error message: java.net.ConnectException: Connection timed out: no further information:
I use the IP to join, which is shown to me on https://www.wieistmeineip.de/. Does anyone know how to fix this error?
With https://www.wieistmeineip.de/ you have to use the IPv4 address.
And how can I get them displayed? I have already tried to enter "ipconfig" in the Windows cmd line and to join with the IPv4 address, but this only works for me and not for other people.
Which port do you have to share?
Port 46851, but I've already tried others
Which port have you set in the server.properties?
This too
Mhm, weird. Try the IP times without the port at the end. Did you also set the UDP port? Otherwise try the standard port 25565
No, I have not released anything with UDP. I selected TCP as the protocol for the port
Then give UDP free.
I have now also released the UDP port, but the problem still exists.
I'm not 100% sure, but I think I can remember that Minecraft uses UDP and TCP on the same port (the one from Config, 25565 by default).
As Moritz5800 mentioned, you need to use the IPv4 address that is shown at the top of the page. If it is not shown there, you may be using a DS-Lite tunnel. In this case, it is not possible to join the server without additional software such as Hamachi (tutorial here:
I changed the port in the server server.properties file and released the port over TCP and UDP.
Then check https://www.wieistmeineip.de/ if there's something from a DS-Lite tunnel or something similar or if the IPv4 address is not displayed. If this is the case, then unfortunately only the approach with Hamachi will probably help.
I'm shown the IP there and otherwise only advertising. I have successfully created a vanilla server on another PC in my network.
That's a big difference. If friends from the LAN (i.e. If they are connected to the same Fritz! Box / router as you) want to join, then you do not need port forwarding.
In addition, it may be that your Internet provider (ISP) has now "switched" IPv4. In that case, unfortunately, bad luck.
What does your IP address look like? Does the colon contain normal points?
Edit: I didn't really want to write a second answer… I wanted to reply to the comment, I'm sorry.
