Description: Your computer is unable to connect to Mojang's login servers, and the error "Can't connect to Minecraft.net" is displayed.
Solutions: Please be sure that you are connected to the internet. If you still cannot connect, our servers may be temporarily offline due to maintenance or updates. You can always check server status from our main page. If we are having an outage, up to date information is sometimes tweeted by our web developers. To see this, you can check out Tobias, Kris, Leo and/or Dan on Twitter.
If you have connected to Minecraft.net at least once in the past, you have the option to play offline for the duration of the outage. Otherwise, please try to reconnect again later.
If your computer's clock is displaying the wrong time, it may not be properly validating Minecraft's SSL certificate. Please be sure that the clock is set to the correct time, date, and year.
If the connection fails, and HTML code is displayed in the news panel, or the news panel has a black background, it may indicate that Java 7 is having trouble using the IPv6 format to communicate with minecraft.net. If this is the case, you'll need to tell Java 7 to prefer to use IPv4 instead of IPv6. Right-click on minecraft.exe and select "Create shortcut". Rename the shortcut to something else, such as "Minecraft with IPv4". Right-click on the shortcut and select properties. In the Target field, replace the text with:
java -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Addresses=false -jar minecraft.exe
If the shortcut cannot find the location of java, try the following location:
"%ProgramFiles%\Java\jre7\bin\java" -Djava.net.preferIPv4Stack=true -Djava.net.preferIPv6Addresses=false -jar minecraft.exe
If the shortcut still does not help, it may be because you do not have the correct version of Java for your machine. Make sure you have 64-bit java if you have a 64-bit operating system.
This error can also be caused by a computer's internet settings, a firewall blocking access to the service, or a special character (!, ñ, ö, etc) in a Windows username. If you have a special character in your computer's username, you will need to create a different username without that character.
