Can't start the game

  • Tech Support section is for getting help with FTB related problems. If there's a repeatable issue that can be labeled as a bug, then please use the issue tracker for the pack or the app at GitHub issue trackers - If there's no repository for a pack that means that the pack is old and/or will not be updated. Bugs for older packs will not be fixed, unless they are critical.

Check you firewall/AV products. Something blocks HTTP HEAD requests.

As seen in line 298, Thaumic Tinkerer seems to be a part of the problem. Try removing it and see if the pack at least starts.
It is still caused by firewall which blocks HEAD request and makes launcher to download wrong file.
