So i have this 1.15.2 minecraft server that i cant get to work properly. I've been desperate trying to fix this. Nothing on the internet helped me so far.
So here I am asking for help. Here's the folder and everything to the server:
The run.bat file:
Here's the server.properties:
I also did the port forward thing. Here's the pictures:
If i check on canyouseeme.org it says that the port is open
So I can join from the pc im hosting it from with: localhost, 0, my Internal IP, my External IP, Internal IP + Port, External IP + Port. Everything.
BUT when I try to join from my laptop to test it if its working from another computer I can join with: Internal IP bcs its connected to the same internet
Internal IP + Port, but when I try to connect with the PUBLIC IP I get from whatsmyip.org i says the following error:
"Internal Exception java.IOException: An existing connection was forcibly closed by the remote host"
I also tried letting every java stuff and ports through the firewall, and also turned off the firewall completely but it didn't seem to help either. I really don't know what seems to be the problem here. I've been trying to fix this for 3 days now and its a pain in the @ss. If you have any idea please tell me what to do. And also sorry for my english I'm not a native speaker.
