This error is officially fixed by the developers, The Technic help discord chat instructed to delete the OAuth folder under %Appdata% : .technic … it will turns your account underaged and needed permission from a guardian account to acess 3rd party launchers, but deleting that folder allowed you to bypass that feature without having to create another account to act as my guardian. If you are still facing the same issue while login to Technical Launcher Minecraft in 2022 you can try the below solutions. There are 2 possibilities for this error:

  1. Problems accessing the authentication servers like a pesky firewall/antivirus or like poor internet connection.
  2. Malware that overwrote your host’s file with a malicious site pretending to be the authentication server.

Open https://authserver.mojang.com/ manually in your browser, can you open it at all? What do you see? Is the connection secure?

Fix 1: I have the same exact problem with the Minecraft launcher. I submitted a problem on the Minecraft forums a couple of months back and had one guy reply with a download to a Minecraft launcher that fixed my problems. if it is any help to fix the problem I have here is a link to the forum http://www.minecraftforum.net/topic/922693-just-bought-new-computer-and-cant-play-mc/page__p__11730472#entry11730472 you will find it on that page post #7 .it is to note that the workaround I used still verifies your Minecraft account and it puts the accentual Minecraft file in a different location.

Fix 2: Since you had a "!" in your username, this will continue to be a problem thanks to java. best bet is to use the instructions found here: http://forums.technicpack.net/index.php/topic,7846.0.html to install the launcher to a different location than the default. that should make it work.
