Error Code IS-EO-Lnc-BldInfo:Http-403

is this Gabe’s curse to Epic game? Tim joking around lead to this? aarrghhhhhh

now i cannot continue dveloping my game as i reinstall my windows and i need that plugin to work…

Hi everyone. I don’t speak English so I’m using a translator. Please excuse any errors… I want to share the solution I found. My computer is Windows 11. Simply closing the Epic Games Launcher didn’t work because I discovered that some processes were still running in the background. So I closed it normally and then opened the Windows Task Manager, went to the Processes tab and ended all processes that started with “Epic”. Only after that did I open it as administrator and that way I was able to install the plugin I purchased.

i just did run as adminstrator + click install from the library but dont use search bar for the plugin just scroll down manually and it worked somehow.

The team is investigating. We’ll provide an update as soon as we have one.

As @SuperTheus mentioned, make sure you’re ending the Epic Online Services Main Service (might be two running) and any other Epic processes running in the Task Manager. Restart the Epic Launcher as admin. Sign-out / Sign-in with your credentials to re-authenticate everything.

I tried that.
I killed all “Epic” tasks in the task manager.
Ran the Epic Launcher as Admin.
Logged out of my Epic account.
Logged into my Epic account.

No joy.

You might want to try deleting relevant files in your epic vault cache and fab library cache. In my case, I completely cleared both caches, and I was finally able to update the Black Eye Camera plugin.

THANK YOU!
Deleting the Fab Library Cache worked for me.

where is that located?

I found it in “Download Settings” which can be found by clicking through “Downloads” in the left nav of Epic Launcher. It has a “Reset” button. And show the path of your cache under “Advance” → “Fab Library Data Cache Directory”. My Windows 11 path is “C:\ProgramData\Epic\EpicGamesLauncher\VaultCache”.

The Reset button didn’t seem to fix anything for me.

But deleting the contents of that VaultCache folder did fix it for me. (I only had “FabLibrary” folder in that VaultCache directory.)

I then was able to install PaperZD to Unreal Engine 5.7.4

I did not need to run it as Administrator.

I uninstalled Epic Game Launcher and re-installed it. That fixed the problem.

Just hit this today. Was playing Fortnite fine earlier and now hit this error. Cannot even uninstall the game either. What a joke.

Tried cache, FAB, Admin UAC and nothing works. How is this unfixed 2+ weeks later? Crazy.

I have just received this error as well - done the Cache, UAC and all other work arounds - has ANYONE gotten a genuine fix for this yet?

Fixed it on my PC (Ryzen 9 5900x | Win 11 | 3060 Ti | 64GB RAM) but my son’s is having the same issue and the workarounds don’t work for him (Win 11 | Intel i5-14400F | Nvidia GeForce RTX 4060 | 16GB RAM)

Yup, same issue is happening to me too. tried everything, and nothing works at all. Hopefully it’s an epic game issue and not an ISP one.

Same thing happened to me. Nothing I did worked at all. Currently patiently waiting for a fix lol. I need to grind my levels this season.

For Fortnite players I found a fix. Go to the store and “buy” Festival or Save the World, (only do one at a time) Then, delete Fortnite. [if it’s acting up then it won’t let you, open the directory and manually delete Fortnite.] After deleting Fortnite the next step is to download the game you selected (festival or Save the World). This will fix it UNTIL you restart your computer. After you restart your computer you’ll have to take the steps all over again until you run out of versions of Fortnite. Best of luck.

STEPS

  1. “Buy” a Fortnite mode such as Festival or Save the World
  2. Delete Fortnite, manually if EGS won’t let you
  3. Install the Fortnite mode (Festival or Save the World, w/e)
  4. DO NOT RESTART OR YOU HAVE TO REPEAT WITH A DIFFERENT MODE (such as festival, reload, or Save the World)

I found a new Fix, none of the solutions above helped but deleting the files in the cache folder triggered the download of entire Fortnite! Now i need to download about 90Gb but atleast somethings worked out!

Same problem? nothing halps
