An existing connection was forcibly closed by the remote host Minecraft Reddit

I run a Minecraft Vanilla Hardcore server since 2013, but since around January, February 2015 I have this problem.

-I tried running the vanilla .exe server on a (Windows 7 x64) and (Windows 8.1 x64).

-I also tried running the vanilla .jar server on a (Windows 7 x64) and (Windows 8.1 x64), with (jre7), (jre1.8.0_25), (jre1.8.0_51).

-I have forwarded my TCP and UDP port 25565 on my server.

It work and have not the message when i reach 127.0.0.1; But... I have the problem when I try to reach it from outside the server, even inside my network.

In the multiplayer lobby it's written: "Can't connect to server". But when I click on the link, it reach a connection, but then crash by displaying the message: "Internal exception: java.io.IOException: An existing connection was forcibly closed by the remote host." and then game never start.

Can't wait for a fix or solution.

"Please help me Mojang-wan, you're my only hope."

I was able to play on my Minecraft server just fine, up until yesterday I stared experiencing sudden lag spikes in half minute intervals. Eventually it gotten to the point where I started disconnected and getting the "Internal Exception: java.io.IOException: An existing connection was forcibly closed by remote host".

Now whenever I join the server, it seems normal, I can interact with things for about 1 minute. Then everything freezes around me for few seconds, and I get kicked for"Internal Exception: java.io.IOException: An existing connection was forcibly closed by remote host".

What is happening? The server is being hosted on a google Virtual machine, and it is a modded server.

Hey there guys,

we've wanted to play Minecraft after long time with my girlfriend, but unfortunately, this error pops up every time when she tries to join any server. Our server is on platform aternos, it worked every time. Do you have any clues how to fix this problem? I've watched lots of tutorials, tried all possible stuff and still nothing happens.

I really need help with this please ;.C

So first of all, im not someone that tends to recur to any kind of forum/support website if its not urgent and theres no more viable option to fix my problem (the mayority of times i use YouTube and try to know about the problem myself)

so just to point out, i already know the 5-7 main posible fixes to this problem, whats more is that i tried them aaaallll, just to give a slight point of view to the fixes i already tried out are:

  1. Change dns to 8.8.8.8 or 8.1.1.8 etc, and dont make it automatically find one.

  2. Turn off windows firewall, i never had windows firewall on, thats because my pc has another firewall provider, but it was one that came wih the pc since i bought it (and it only lasts 7 days once i restart this computer) so in conclusion i dont have any firewalls.

  3. Internet Provider, at first i thought it could have been this, so when i searched up for it it said to use my phone mobile data and join, it didnt work, so if it isnt my internet provider it has to be my computer right? but what?.

  4. Delete and Re Install both java and minecraft, did this twice, and didnt worked out.

  5. Check the box on Java properties that says "(native sandbox), tbh i dont know what this is for but it didnt work either.

  6. Type windows + r, and type "cmd" then type "ipconfig /flush", something like that and it didnt work :C.

  7. now at last i found that changing the server view distance to 4 might work, it didnt work.

I had no problems during the first 2 days the server was up, its more i didnt even had high ping or anything related, my internet network is just fine, so i dont even have a clue of whats going on, if someone has any new fix or tip for this, it would be godly, any response is much appreciated.
