Fab plugin can't open

Hi all,

This error window keeps popping up when I open Fab plugin for UE5.4. I can’t actually use this plugin. None of the links in the window works. Is this a bug or did I miss something ?

Hey there @NEROMIYANO! This could be related to a known launch bug.

Are you by chance on MacOS? There is currently a handful of issues reported for the plugin and MacOS users for both using the plugin and retrieving the manifests for downloads.

No, I’m on Windows 11.

I’m having the same problem since yesterday. Also on Windows 11. Did you find any solution so far?

I am having the same problem, anyone manged to solve it yet?

It’s happened twice to me already that the plugin doesn’t open (the generic “Oops! something went wrong” and the only way to make it work again is by uninstalling it in the Epic Launcher and installing it again. Do you know of any other solution? Thanks.

I’m having the same issue. I’ve already uninstalled and reinstalled the plugin, but the problem persists. I’m using Windows 10 and Unreal Engine version 5.4.4.

Hey there @Artur_R, @Coe140bpm, and @marcio.buto Welcome to the community! There have been some changes that may have corrected this on the resource backend. Has this been solved for anyone?

Iám having the same problem for 4 days

Hi @Lamaral14 !

This may sound like an oversimplification. But, are you logged in when this occurs?

Any fixes? Tried updating engine, logging out/in of the epic launcher, disabling/enabling plugin and still nothing working

yes

H there @JAndreason

Welcome to the forum! I tried pulling some additional information on this and found a few threads over on Bug Reports where users are discussing possible solutions and letting the devs know of the issue. I can't access There’s a link to it. Some users were able to resolve it with different methods. I haven’t found a one-size-fits all approach on this one yet. But, I’m continuing to research it. I’ll update the thread here with my findings this week.
