So starting about an hour ago I started getting a "Login failed due IOException" error. However this only happens when using the FTB launcher. I can login using other launchers so it only seems to be an issue with the FTB launcher. I've checked my antivirus/firewall logs and it's not blocking anything from the launcher.
You can find the output from the FTB Launcher console here: http://pastebin.com/embed_js.php?i=yW3gTVRM
