FAB Plugin does not work in multiple ways

Development Pipeline & Plugins
1

Since its release, the FAB plugin does not allow me to log in 99% of the time, just redirecting to an infinite loop of “Verify that you are human”. On the three or four occasions that I have managed to log into the plugin in engine, there is nothing in my library and any asset from the main ‘Discover’ section just loads infinite grey boxes which never resolve to anything. Going back from this point while logged in results in the infinite “Verify that you are human” loop from Cloudflare once again.

This is while logged into Fab in the browser with no browser addons running on the page.
Is there any awareness that this plugin doesnt work at all with EPIC ? It is literally useless and will account for many lost sales.

This does not appear to be a widespread problem, so it may be specific to certain setups or configurations. Could you please provide any details if you’re on a restricted network e.g on a VPN or behind a firewall?

We are very frustrated as it has wasted 1 week for us. We have tried everything but it doesn’t seem to go away.
Its very persistent and needs someone from your side to look into it.
We are not using VPN and fab is working perfectly fine in Chrome and Edge both, it is only happening in FAB Plugin that runs inside the Unreal Engine and we do not know of any way to debug this.

We do not see any options to clear any cache or cookies, please explain how this works and how can we resolve this?

@anuj-aggarwal I’m sorry to hear about the issue you’re facing. Could you please submit a bug report here with the exact steps to reproduce the problem and the following details:

  • Are you accessing UE through Epic Games Launcher? If so, what is the Launcher version?
  • What UE version are you using?
  • Are more people on the same network impacted by this issue?
  • What are your machine and graphic card specifications?
  • Can you check the output log in UE and confirm if the token state is ‘Valid’ and the token is received (look for UserAuthGenerated: Received FUserAuthToken)?

Okay sure we will create an issue on the link provided.
Here are the details:

  1. We are using epic launcher version 17.2.1-38570976+++Portal+Release-Live.
  2. Unreal version is 5.5.1.
  3. No this is happening on a specific system and we tried running on the different setup and it was working there.
  4. Machine specs are:
    i7-12700k 3.6GHz, 64GB RAM, RTX 4070 ti
  5. These are the logs which I found when I searched for UserAuthGenerated:

LogEOSSDK: LogEOSAuth: UserAuthGenerated: Received FUserAuthToken
LogEOSSDK: LogEOSAuth: UserAuthGenerated: Login complete: EOS_Success
LogEOSSDK: LogEOSAuth: UserAuthGenerated: Device auth to be continued at:
LogEOSSDK: Warning: LogEOSAuth: UserAuthGenerated: Account Portal overlay failed to load for device auth continuation; falling back to browser based flow
LogEOSSDK: LogEOSAuth: UserAuthGenerated: Received FUserAuthToken
LogEOSSDK: LogEOSAuth: UserAuthGenerated: Login complete: EOS_Success

When I had Fab plugin enabled I also see this warning msg:
LogEOSSDK: Warning: LogEOS: Error response received from backend. ServiceName=[Friend], OperationName=[GetBlockList], Url=[], HttpStatus=[403], ErrorCode=[errors.com.epicgames.common.insufficient_scopes], NumericErrorCode=[1056], ErrorMessage=[Insufficient access scopes. Expected: [friends_list]], CorrId=[EOS-EpHCPPe17k6dWoE0bOSBdA-mhqHbRBGMU2RtEBcNgCSiw]

If i disable fab plugin this goes away. I did not check, though, if it was showing on the other setup as well where everything worked.

Hello, This is also happening to me in the same way. At first it asks to ‘sign in with your epic games account to access fab’ through a web browser, I click accept and am brought back to the fab plugin.

Then a window comes up and says ‘This is your first time you login into Fab? Please try to login first on website to activate your account’ and asks to visit the fab website or reload the plugin.

When I press reload the plugin a cloudfare window pops up in the plugin with a check box to verify that I’m human. Pressing it however has never worked and loops infinitely as described by the other poster.

However I’ve noticed that this is only happening on a large project of mine that I’ve updated through a few unreal versions. in new projects or other existing projects I’m signed into the plugin just fine. This problem was happening in 5.4, I updated to 5.5 and it’s continued to happen.

I’ve tried deleting the file webcache_4430 in the saved folder (and the entire saved folder) and the issue has persisted.

In my output log I am seeing UserAuthGenerated: Received FUserAuthToken
I also saw this in the output:
LogFab: Display: Logging in using persist
LogFab: Display: User logged in

Let me know what else I can share with you, thank you.
