Forge 1.13+ is currently not supported by the Launcher. No ETA for a fix.

Get offline java (https://java.com/en/download/windows_offline.jsp) and allocate 2-3 GB RAM in Launcher Options -> Java Settings.

Nah, that modpack requires more than 2 GB ram.

Downgrade your java to 8u51.

So uh. I downloaded the same modpack you were using. I removed the older forge, and added the same forge you are using. Got it started for a bit before the older Optifine version broke it.
Quite unsure what you did so it doesn't work. The error in your log usually means wrong Forge/Minecraft version.

Dropbox works fine. Just make the download link, manually change the 0 to a 1.

Use 64bit java (you are using 32bit). To install that, download the OFFLINE installer from java.com.

No, you are trying to make a 1.13+ modpack, and Forge simply doesn't work anymore with Technic Launcher for 1.13+. ETA to be fixed: Never.

So, that happened after you added MoarSigns (and its obviously from 9minecraft, baaaaad) to the server, right?
Your VERY old version you got off 9mc: https://www.curseforge.com/minecraft/mc-mods/moarsigns/files/2223209
The actual next version uploaded 3 days later: https://www.curseforge.com/minecraft/mc-mods/moarsigns/files/2223519
The actual latest version that's not from the start of 2015: https://www.curseforge.com/minecraft/mc-mods/moarsigns/files/2284576

Technic, like Atlauncher and MultiMC, do not support Forge for 1.13/1.14/1.15 due to how the forge installation has changed.

You appear to be having an issue with an unsupported Intel Graphics device and Windows 10. This issue is common for older computers and Windows 10. We recommend, if it's a desktop, to get a dedicated graphics, as it is always a better option, anyways. However, there is a fix. Please press WindowsKey + X and click on "Programs and Features" and uninstall all copies of Java. After that, install Java 8 from this link: http://javadl.sun.com/webapps/download/AutoDL?BundleId=98428 Start up the launcher and try again.

Hello, I'm HiNiceUsernameNowMine, you seem to miss some mods.
First, download these two. No 9mc mods please.
https://www.curseforge.com/minecraft/mc-mods/not-enough-items-1-8/files
https://www.curseforge.com/minecraft/mc-mods/codechicken-lib-1-8/files
Now, add this mod: https://www.curseforge.com/minecraft/mc-mods/notenoughids/files/2695044
Once you've done so and tested, please report back.

Eh. You actually got 3 issues.
1. Your graphics drivers are outdated (Intel HD graphics), and this is due to you likely having upgraded this computer from an older windows version to Windows 10.
2. If updating graphics drivers doesn't work, you'll have to downgrade your java to 8u51/8u25, as that's the last update that worked in this case.
3. You'll need to use java 64bits. The link in point 2 already provides a 64bits option. Currently you are allocating 512 MB, which is nowhere near enough RAM to use modded 1.12.2.

There's a Open Logs button under Launcher Options. Use the relevant day's log. Upload it to pastebin.com or paste.ubuntu.com (if too large for pastebin). Share the link here.

Remember that part where it said to name the file "modpack.jar"? In your case, only name it "modpack".

Eh, its what you get after the gazillionth case of this...

Canned response from one of our bots:
Please download this file, then RightClick->Run as Administrator. This should clear Java Settings that are being stored in your OS, which interfere with Technic. This script was written by the main author of this bot, Khio, and can be trusted. http://download.uskarian.net/technic/clearJavaEnvVars.bat

Get java 8 64bit. Forge will not work with anything higher than java 8. https://java.com/en/download/windows_offline.jsp

Yeah, its so weird you get a vanilla server when you boot up the vanilla server. Where'd your forge server go?

Considering all the version info from the mods is gone, I'd say that you didn't get those mods from Curseforge. Or from Coro's site, the dev of weather and storms (called weather2). YOu oughta take a look: https://coros.us/mods/weather2

That's because its not a solder modpack.

Sigh. Only use Curseforge for your mods.
You included mods from 9mc or similar that are already included in the modpack. Couldn't tell exactly which mod versions from 9mc, as that stupid site removes those.

No you do not need a 2fa code.

Nope. No help whatsoever for Pixelmon.
Now if it was any other modpack, I would suggest you go to Modpack Options, press Specific Options and choose the version I want to play, then press Reinstall Modpack. But nope, not going to tell you how to do exactly this now that you said you are playing pixelmon.

So, what does it say in the lower right corner of the launcher?
