Can you post your crash report please?

This is where the exception is being thrown, I would suggest moving your simplyjetpacks config(including your custom jetpack) out of the minecraft installation, having the mod make a fresh one, then re-applying your changes manually with the moved copy as a guide.

I'm not seeing the same issue on my end, however I noticed you're missing all your gradle stuff in the repo, could you please add that.

There is also the fact that Google is enforcing SSL if people want to get Notifications in Chrome, they don't let you enable it on non-SSL sites.

I've seen some text editors insert symbols because the text encoding wasn't correct, double check that they're UTF-8.

Is the source code on github?

Have you tweaked the SimplyJetpacks configs? I'm seeing exceptions from the config loaders of SimpleJetpacks and JourneyMap.

The other person is connecting to the server... not to your client, the server would know more about the exchange than your client would. Please excuse my dumbness sometimes

This looks like a client log, can you provide the server log? In regards to the file size issue, could you try using GitHub's gist service and see if it accept the full file?

We mean the log file, not what you see in the console window, if you're using the vanilla launcher with forge on Windows you can open the run prompt (Windows Key + R) and type %AppData%/.minecraft/logs then click "run" and this will open the logs folder, what will help us most is the fml-client-latest.log file, and again, please use a site like pastebin rather than uploading the file.

1. This thread is almost 4 years old, if you have an issue please make a new thread. 2. If your issue is with a 1.7.10 version, please update or you will not get much help.

What I've done in the past to update the forge version is simply get the updated mdk and unzip it into the project, then run gradlew setupdecompworkspace --refreshdependencies

Just run the installer, the only requirements for it to work are a working internet connection and java (which is a requirement for minecraft anyway). Note that when I say "run" I do not mean unzip, I mean run it as a program, by double clicking, or from the command line like this if you have the jar version of the installer.

What do you mean by "archives of forge"? Are you looking for a zip that you can extract or unzip and have a working forge server?

Assuming you are running it through the command line, add -Xmx to specify the max you will give the server. Note that this is the same method as a vanilla server Example: java -jar forge.jar -Xmx3G will give the server a max of 3 Gigs to use

Please post your fml-client-latest.log

@lyghtningwither The Yggdrasil thing is a matter of how fast your client makes requests to Mojang's authentication servers, if you don't see the exception then your client is probably just giving enough time between the requests that the server's don't complain. From what I've read elsewhere the client should catch that exception and basically say "Oh ok, I'll wait a bit and try again"

Stab in the dark, have you tried updating your graphics drivers?

When the "Not Responding" window comes up are you giving it time or quitting as soon as you see that?

If you want to make a Server-Side GUI I don't think you can use anything from Minecraft's built-in GUI Utilities, you will likely need to build one from scratch. Edit: I am an idiot who did not read the whole thread

It looks like CustomNPCs errored out Forge and it propagated because dependencies

Aren't the mods with updates available the ones that have emeralds next to them in the mods list?

I just grabbed the latest version of forge, ran a test and in the quick test I did the lower-case-named en_us.lang worked fine.

Two mods are trying to register the same metal with Tinkers, you'll have to choose which one to use or check the config for both mods to see if you can stop one of them from registering it.

Try this (in a spoiler because YouTube player is obnoxiously big):
