We need your unmodified Technic launcher log file in order to further help you.:
1.) Start the Technic launcher
2.) Click on the button in the very top right of the launcher called launcher options 3.) A window should appear
4.) Click on the button in the bottom left corner called open logs
5.) Find the log file dated for today(techniclauncher_YYYY-MM-DD.log). NOT the log file from yesterday, the week before or last month!
6.) Now attach the files and reply back to this post.
I'd also like to mention that you can join our discord server and drop your logs in #help for faster and easier support.
