Problem 2 Of my pack won't start up

  • 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.

I downloaded 2 modpacks from the "CurseForge Modpacks" those are "Running Red" and "Crash Landing" those 2 packs refuse to start, the MC launcher opens but when I click play they won't start. i've been looking for help but no one had the exactly same problem, I downloaded a FTB pack "SkyFactory 3" it works, I played yesterday so maybe i should ask for help in a curseforge forum???
IDK can anyone help me here? I'll attach my debug log.

The 2 modpacks worked for me a while ago in the FTB old launcher v1.5.1 that launcher allowed you to download the pack with a code, maybe thats the problem the new one gives you the pack without a code, maybe that pack isn't full.
I'll continue to use that old launcher until i found the solution.

If you're having issues with packs not made and updated by the FTB team this is not the place to ask for help for them. However, the debug says it can't connect to Minecraft connect which needs to be synced or logged into.

Sorry I had a mistype its a mod called MineTogether and you need to log into it for it to sync. I don't know how you would do that with the curse launcher. For the FTB launcher, there is a login button that links you to the website to log into it. However, while relooking at your debug log I don't think that is the main cause. I think it might actually be a pack downloading issue so I would go to whoever hosts this pack for more help. Here is why:

Code:

Not being able to download these Java files is most likely causing your crash on launch. Wherever the pack is trying to grab these files from doesn't see it
