      Potential Cause

      This Issue is potentially caused by Antivirus Programs and/or Firewall Programs, especially Norton. Try disabling it while launching Minecraft and see if it helps. If it does maybe consider using a different Antivirus Program.

      Also, this issue might easily be fixed by reinstalling Minecraft.
