I have a major issue that just popped out of nowhere: After I watch Youtube or do intensive activity on my computer, when trying to connect to my favorite server I get the error      java.net.ConnectException: Connection timed out: no further information: play.opcraft.net/31.220.14.118:25565   I have searched on Tom's Hardware and the Minecraft Forums for common solutions like adding inbound UDP and TCP rules for port 25565 but to no avail. Others said turn the chunk render down to a low setting, but that also didn't work. I'm honestly out of tricks and don't know how to solve it.  This just started happening about a week ago and its never done it before. I've tried to reset the .minecraft folder and it didn't work.   The only thing that does work is restarting my computer, which is getting annoying every day. If someone has a solution, can you please help me.

I can join the server and sometimes the map would load for the server but i would just fall through the map and it would dissconect me and say timed out, any solutions?

I have looked all over the Internet for solutions but I have got nothing.  I want to install the minepainter mod but I need a META-INF folder and a minecraft.jar.

I am trying to connect to my friends Hamachi server, but whenever I go to my sever selection, it says can not connect. Is there something I am doing wrong? I have been using his server for a while, and this just started happening. I can connect to my other servers, but that one is not working.   Here is his server.properties:  #Minecraft server properties #Sun Dec 02 12:50:07 EST 2012 generator-settings= allow-nether=true level-name=world enable-query=false allow-flight=false server-port=25565 level-type=DEFAULT enable-rcon=false level-seed= server-ip= max-build-height=256 spawn-npcs=true white-list=false spawn-animals=true snooper-enabled=true hardcore=true texture-pack= online-mode=true pvp=true difficulty=1 gamemode=0 max-players=20 spawn-monsters=true view-distance=10 generate-structures=true motd=A Minecraft Server

Me and my friend don't play on realms, but we can join each others world on Minecraft Pocket edition. The thing is he can always easily access my world, but sometimes I can't always get on his world. It's odd actually, once when I was trying to join his world the screen just went blank.  Instead of loading the server/world, where is the dirt background and it writes "locating server" on it but, it didn't show the "locating server". It just displayed the dirt background. Then it said: "unable to connect to world". Even though we both have the same version of Minecraft Pocket edition. My question is: How come I can't join his world?

I am getting the following error when I try to connect to a Minecraft server:  This is all servers, not just one. The error says:  io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection refused: no further information: Version 1.12  I've tried:  Restarting Minecraft Restarting Computer Uninstalling and Reinstalling Mincraft Uninstalling and Reinstalling Java Altering Firewall Restarting Internet I've messed with my port, made a second windows account, reset netsh winsock Checked hosts Made a new WINDOWS account  The overlay in the bottom right is Geforce's Overlay for game capturing. I don't have any mods installed. A Mojang support ticket wouldn't help. Im desperate.

Minecraft's got an "Open to LAN" feature, which can be used to set up a local server when two computers running Minecraft are on the same network. Some young relatives of mine use this to play together whenever they're in the same house, but they'd like to be able to play together from their respective residences.  A server is not optimal because it's a bit complex. I've tried using Tunngle to spoof that the computers are on the same connection to no avail.  How can I convince Minecraft's "Open to LAN" that their two separate computers are on the same network?

I want to create a new world on our Minecraft server, but exploring a new map and generating terrain causes massive lag.  Is there a way to pre generate the chunks (with the default map generator) in a specific radius around the spawn?  I'm looking for a Bukkit plugin or tool I can use on our Linux machine. An offline tool I can run on my local machine is ok, too.

I quit and restarted Minecraft because it was being slow/lagging a lot to see if it would help.  Unfortunately, when I opened it up I was logged out and every time I try to login it gives me this message:     Username or password incorrect!   So, I re-typed everything and made sure to type it all correctly and it still won't let me log in. I also noticed that as soon as I hit login the password becomes blank.   I have purchased the game so it's not like a trial has expired or anything like that. What can I do to fix this?

My LAN server won't let my cousin join me or me join my cousin. It won't show up on the multiplayer screen - it keeps saying "scanning for LAN servers" but it never finds it. I am at his house and we use different computers but it won't connect. How can I fix this?

I've gone into the Nether and seemed to have lost my portal out of it, I also can't die in lava or by mobs attacking me, I'm appear to be invincible and can't die.  This is Single Player by the way.  Why is this happening?

My friend had hosted a Minecraft server before and brought it back up today with my help. He and anyone in his LAN can connect. However we have had a few people try to connect, including me, and when we try to connect it gives the message:  Failed to connect to the server Connection timed out: connect  What does this exactly mean? How do we fix this?

I can't connect to  or  &mdash; the initial connection times out every time. I check this every week, and it worked fine last time, so it must be something pretty recent. (Further HTTPS deployment?)

On both my computers, the entire internet connection goes down when the Minecraft Server crashes. A reboot is needed to get the internet back.  Error is something like Internal exception: java.net.SocketException: Connection reset by peer  Why is this and how can I stop it?  EDIT: PCs are both XP SP3 and have RealTek integrated network cards  EDIT #2: I am accepting @Oak's answer since it a good summary for this problem, however in my case I deleted %appdata%\.minecraft\bin\minecraft.jar and let the game recreate it and it seems to have fixed the issue. At least for 2 people on a local network.... we'll find out later if it comes back when we get a few more friends on the server using our public IP.  EDIT #3: Problem came back again with more people on the server however the app linked below by Oak to buffer network packets fixed it

I am using a premium legit version of Minecraft that I purchased. I can log into minecraft.net as well as mojang.com but I am unable to login to Minecraft the game through the minecraft.exe or the Technic launcher. The Minecraft servers are up and running fine. My internet connection is also fine. I double checked my credentials and even tried changing my password. I tried using both my username and my email. I tried all of this on two separate accounts that I own. I tried deleting my login, launcher, launcher.pack.lzma, and launcher_profiles.json and then reopening Minecraft. I tried re-downloading minecraft.exe.   Nothing has worked and I seem to have run out of options. I sent a help request to Mojang but in the meantime I was hoping that maybe you guys could offer some advice.

What do I do? I looked at a similar question to mine and there was an answer saying to make sure Java is allowed past the firewall. So I checked and it already is. I've tried uninstalling and installing both Minecraft and Java but nothing has changed.  says that all services are fine, so what's going on? I bought a 2nd account to use as an alternative in-game account and now I can't log in.  (I cleared the email and password boxes for obvious reasons in this screenshot: security purposes)

Every time I hold button 1 to break a block it sends me to the menu screen.  I can't figure it out so its impossible to play classic.  I've tried re installing Java 7 but that didn't change a thing, and changing game quality didn't do anything either.  I want to play minecraft but can't unless this is fixed.
