Forge Installation Error - "Unable to find valid certification path to requested target"

Recommended Posts

I downloaded the recommended version of Forge for 1.19.2. When I pressed "install client" it was downloading but then it said "Failed to run processor: javax.net.ssl.SSLHandshakeException:sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target" 

I'm not sure how to fix this problem.

Hi!

It looks like you're having issues installing Forge. In order to root out one of the more common issues, we'll need to see your hosts file.

Here's the steps to getting this file.

1) Press the Win + R key on your keyboard.
2) Paste the following into the prompt that opens: notepad %windir%\system32\drivers\etc\hosts
3) Use Ctrl+A to select everything in the file, then Ctrl+C into the textbox to post to this thread.

Looking forward to your reply!

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

    • Hello. I'm using IntelliJ IDEA and making a mod for Forge 1.20.1 and I'm trying to make a GUI. I found that the Minecraft-related codes are all obfuscated and when setting up the workspace, Gradle did not execute Deobfuscation tasks like createMcpToSrg. Is this normal or a bug? Can anyone help me with this?
    • Hello! I'm trying to get a list of all entries registered in the infusion upgrade registry. Code can be found in github: https://github.com/ChamoisEST/MiningMadness/tree/1.20.1 Registry in common/registries/MMRegistries.java Event that calls the registry is in MiningMadness.java List of registered entries should be called in common/capabilities/infusion/InfusionCapabilityImplementation.java:getActiveInfusions() in the for loop. Is there any way to accomplish that? Thanks in advance!  
    • So, I am trying to create and add tags to my custom damage type, but looks like I made something wrong, since it crashing with error that "cannot register" damage type. Im trying to register it, and in datagen add tags, but it everytime crashing due to not register "grimtales:entropy". Full code there - https://github.com/undertakerJ/Grim-Tales-Forge ModDamageTypes class public class ModDamageTypes { public static final DeferredRegister<DamageType> DAMAGE_TYPES = DeferredRegister.create(Registries.DAMAGE_TYPE, GrimTales.MOD_ID); public static final ResourceKey<DamageType> ENTROPY_KEY = ResourceKey.create(Registries.DAMAGE_TYPE, new ResourceLocation(GrimTales.MOD_ID, "entropy")); public static final RegistryObject<DamageType> ENTROPY = DAMAGE_TYPES.register( "entropy", () -> new DamageType("entropy_effect", DamageScaling.ALWAYS, 1f, DamageEffects.HURT)); // // public static final DamageSource ENTROPY_SOURCE = new DamageSource(Holder.direct(ENTROPY.get())); public static void register(IEventBus eventBus) { DAMAGE_TYPES.register(eventBus); } } Datagen for damageTags public class ModDamageTagsProvider extends DamageTypeTagsProvider { public ModDamageTagsProvider( PackOutput p_270719_, CompletableFuture<HolderLookup.Provider> p_270256_, @Nullable ExistingFileHelper existingFileHelper) { super(p_270719_, p_270256_, GrimTales.MOD_ID, existingFileHelper); } @Override protected void addTags(HolderLookup.Provider pProvider) { this.tag(DamageTypeTags.BYPASSES_INVULNERABILITY).add(ModDamageTypes.ENTROPY_KEY); } } Datagen class it self   @Mod.EventBusSubscriber(modid = GrimTales.MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD) public class DataGenerators { @SubscribeEvent public static void gatherData(GatherDataEvent event){ DataGenerator generator = event.getGenerator(); PackOutput packOutput = generator.getPackOutput(); ExistingFileHelper helper = event.getExistingFileHelper(); CompletableFuture<HolderLookup.Provider> lookupProvider = event.getLookupProvider(); generator.addProvider(event.includeServer(), new ModDamageTagsProvider(packOutput, lookupProvider, helper)); } } And register class in main class public GrimTales() { IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus(); ModDamageTypes.register(modEventBus); modEventBus.addListener(this::commonSetup); MinecraftForge.EVENT_BUS.register(this); modEventBus.addListener(this::addCreative); }

    • Hi. I'm trying to play RLCraft with Optifine but my game keeps crashing on startup with Exit Code 1. The modpack was working fine yesterday, not sure what changed to make it not wanna work anymore. I was hoping someone here could help me figure out what's going wrong. If I remove Optifine, nothing changes, I still get the same errors. Thanks in advance. Crash Report (I only included the errors+fatal, I’m not sure if more is needed, please let me know): https://pastebin.ai/66ivknz0f4
