Launcher Version: 1.0.1.3 Operating System: Windows 7 64 Bit Java Version: 1.7.0_04 Antivirus Program: I am using a Proxy to start the Technic Launcher, as I am trying to play at my workplace (in break, of course). It does work quite good with Minecraft, but the Technic Launcher shows the above Message. I am also able to see the Images on the sides in the Launcher when I launch it with the proxy-command, which doesn't happen normally. Is there any other way to authenticate with Minecraft.net to be able to play Minecraft? The Command I use is this (Company name removed): mkdir %appdata%\.techniclauncher\rtemp java -Dhttp.proxyHost=<Proxy name of my company> -Dhttp.proxyPort=8080 -Xmx800m -jar technic-launcher-latest.jar Description of Problem: I am using a Proxy to start the Technic Launcher, as I am trying to play at my workplace (in break, of course).
