Your problem is already fixed probably, but for the people who are searching for a fix, follow my steps

  1. Search for CMD and run it as administrator
  2. Type in the bar: netsh winsock reset
  3. It should be fixed!
  4. If it still doesn't work, try contacting Mojang, the creators of Minecraft

My husband is having trouble connecting to my server when i try to open to Lan. It was working yesterday and now after turning both mine and his pc’s off for the night he cant connect.
He keeps getting this error:
java.lang.nullpointerexception: group
Sometimes on my screen i can see that he has joined the game, then a second later it reads that he has left the game. On his screen it just says "Failed to connect to the server disconnected”
Hope someone can help :)

when people try to connect to my server, they receive this error message
internal exception java.lang.nullpointerexception can not invoke "net.minecraft.nbt.compoundtag.m_128459_(string)

i also received this error message as well but during this test for some reason it let me join the server, i've tested this out on singleplayer as well and the world works fine nothing seems to be corrupted it just doesn't work for the server.
we've also made multiple worlds for this specific pack i've made and they all have had this problem, randomly sometimes people will be able to join and play normally but other times they get this error and they cant play.

r/Minecraft on Reddit: Help Minecraft Server 1.20.1 java.lang.nullpointerexception after reconnect.
November 3, 2023 -

I created a local minecraft server dedicated to Mojang's own Server.jar and added some mods and it worked perfectly, but sometimes when disconnecting we were unable to reconnect (including me on the same machine as the server) and we kept getting the error java.lang.nullpointerexception but after a random amount of time we managed to reconnect. If anyone knows why this error is occurring and could help us, I would greatly appreciate it.

Edit: The problem was the mod skin changer, after removing it it worked normally. Thanks for the help flanigomik.

May 9, 2024 -

So I created a server with mods, actually, alot of them.

And I play it with friends, but the thing is, whenever a new player joins the server and is in view range of one another, the player that was online is kicked off with this message of error. It doesn't stop us from playing since to fix it we just have to join again shortly after and it's "fixed" but It's really bad to just have people being kicked out from the server... Anyone know what could help?

Obs:

  • Only happens when the person who joins or the other player is in a certain range of each other (example: if i try to log in with a player 3 blocks beside me and another 900 blocks away, the player in my view distance will be kicked, but the other one won't.);

  • If everyone that was kicked off logs in shortly after, the error doesn't happen to anyone (a window of roughly 20 secs);

  • Everyone lowering their Render Distance won't work, as we tried and it might have a minimum distance for the error to happen, not too short but not too long.

Logs here (edit: I fixed the logs, now its the right one)

If anyone can help, I would greeeeatly apprecciate it! (Srry for english errors, I'm a Brazilian on the learning curve :P)

r/learnprogramming on Reddit: [Java] Can someone nullpointerexception to me in layman's terms?
March 5, 2020 -

Here is a code block from one of my CS professor's slides:

String[] words = new String[5];
		System.out.println("word is: " + words[0]);
		words[0] = words[0].toUpperCase();

When I run it I will inevitably get:

Exception in thread "main" java.lang.NullPointerException at Example.main(Example.java:8)

Why is this? What I understand so far is that basically, null is a variable that exists but does not hold a value. He also includes a visual representation of what is happening and I think I sort of understand what is happening but I was wondering if someone could tell me specifically what I am telling the compiler to do and why it throws an error upon compiling? In other words, what am I telling a computer to do here and why does it respond by telling me it can't do that?

What I understand so far is that basically, null is a variable that exists but does not hold a value. Hmm, not exactly. null as a concept represents the absence of a value. null is materially different than 0, or an empty string (""); those are values. null means "no value". Now, to really understand what a NullPointerException is, you have to understand what a reference is. When you say this: String myString = "Hello World"; You are creating a block of memory somewhere in your system's memory, and storing the data "Hello World" inside it. Then, it's taking the memory address of that block of memory and storing it inside a variable called myString. When you use myString, Java is dereferencing that memory address and using the value stored there. When you pass the variable to a function, you aren't copying the string, just the address of the string. This address is considered a "pointer" to the real value. But, what if you wanted to have a string variable but you don't want it set to anything? Or just haven't set it to anything? String myString; What value does this hold? Well...it doesn't. It is null. What null actually maps to is a memory address of 0. i.e. not a real address; it lets the system know that "this is not a value". When you create a string array, each cell of the array is a block that can hold one of those addresses. But by default each cell is unset; therefore null. When you call this code: words[0].toUpperCase() You say "get me the string in the very first cell of the words array. Then dereference it, and call toUpperCase() on it." But since it doesn't actually point to a real block of memory, it can't call toUpperCase() on it because "it" doesn't exist. So it crashes. Hope that helps.

A null pointer exception is kind of like mailing a package and not putting an address on it. Where is supposed to go? You can’t deliver to (blank) so you get an exception (return to sender). I think your professor gave you a code snippet and not a full working program, so to run it you’d have to put it inside a program of your own. That or it’s intentionally giving an error to demonstrate that error.

Hi!

I have been playing the RAD (Rougelike Adventures and Dungeons) modpack for Minecraft this week. The mod has been working great. There has been an occasional lag, but nothing to complain about. To overcome this occasional lag, I restart my computer and it always works fine. I restarted my computer this time, opened RAD, and it crashes and gives me this error:

Below is the crash report:

And here is the latest log file:

https://paste.gg/p/anonymous/42d7108f74974297bc7ba19d044f09e8

RAD runs on Minecraft 1.12.2, and the RAD version is 1.49. I also use Curseforge to start the mod. I appreciate any help with this!!! Let me know if I need to add anything or if you need more info!

Thank you so much!!!

r/Minecraft on Reddit: How do I fix java.lang.NullPointerException crash?
November 29, 2017 - Everytime I load up FTB Revelation through the twitch launcher the game will start loading and sometimes it won't load all the way and sometimes I actually get to the menu but I can't play single player or multiplayer. When I try to play either the error will just pop up. So far I have tried to uninstall everything related to minecraft and then reinstalling it. I've updated Java, I've tried to add more ram into it, and I've tried to change the code in the files.
