When you uninstalled Java you uninstalled them all at once, right? You didn't reinstall one by one?

If you go to https://maven.minecraftforge.net in a browser (ignore the auth prompt, you don't need it for this) and check the certs are they all valid?

Certs is one of those things that is shared I think, so to reset it you might have to uninstall every JDK and JRE until you don't have Java, then install the JDKs (JDKs have JREs in them, no need to get separate ones)

It's better to download the translations during build and package them in the mod rather than downloading them at runtime

Threads merged. Taking a look at the log... Edit: Have you made any changes to the packs at all?

My signature has instructions for getting a log out of Curse

What did you download? Forge itself or the MDK?

Why are you building the mod from the repo? https://www.curseforge.com/minecraft/mc-mods/tinkers-construct/files/3281505

The maven is not meant to be accessed manually. Only the human-readable portions require auth, the part that serves the files is perfectly accessible without auth.

I'm afraid we have no idea what causes this and without a way to reliably reproduce it there's nothing we can do other than recommend using Mojang's own launcher

Please provide debug.log (more info on where it is and how to provide it in my signature below, just expand the spoiler)

"Read timed out" for a network operation is rather easy to Google

Did JarFix report success or failure?

Are you a player or a mod dev?

The Forge maven has moved from https://files.minecraftforge.net/maven to https://maven.minecraftforge.net, you'll need to update your build.gradle to reflect this and possibly run gradlew --refresh-dependencies to tell Gradle to get the updated ForgeGradle
