Hello,
When I create new projects (VR template), the convai editor UI inside UE just loops on authentication and doesn’t ask for credentials. I don’t have the possibility anymore to add my convai API key to my project as it’s supposed to be automated now (that’s what it says at least in the API key field). My old projects still work fine as the API key has been set.
Steps followed: create new VR template, add convai in the plugins, restart project, upon restart a convai window pops up: “Welcome to Convai … Connect Convai Account” I press it → initializing convai → Authenticating… (and goes on forever)
I tried this on multiple desktops and my pc, same results (always logging out of every account)
I am working in UE5.5.4 with convai 4.0.0-beta.11

When you log in, does it get stuck on the “authenticating” screen? How are you logging in?

I am logged in in my epic games account. For the convai side: I’ve tried being logged in and out in the web browser, however inside of UE I never get logged in to my convai account. I just get this sequence:
“Welcome to Convai … Connect Convai Account” I press it → initializing convai → Authenticating…
And it stays forever stuck on Authenticating

For now, you can add your API Key by manually.
“{Project Name}\Config\DefaultEngine.ini”
Under **[/Script/Convai.ConvaiSettings],** you can add your API key.

Hello, I’ve been having this same problem with convai on UE 5.6. I put ApiKey={My ApiKey} under [/Script/Convai.ConvaiSettings] in DefaultEngine.ini using notepad and after saving and launching, it still prompts me to connect convai account.

Please download the file from this [link](https://github.com/Conv-AI/Convai-UnrealEngine-SDK-V4/releases).
Open the project root directory and create a folder named Plugins.
Then extract the downloaded file and drag the Convai folder into the Plugins folder.

For now, please use the following workaround.
If you are using the Marketplace version, open this file:
`C:\Program Files\Epic Games\UE_5.X\Engine\Plugins\Marketplace\AIforNPCb346e0c968b9V8\Config\ConvaiEditorSettings.ini`
If you installed the plugin from GitHub, open this file instead:
`{}\Plugins\Convai-UnrealEngine-SDK-Dev\Config\ConvaiEditorSettings.ini`
You can also check this path:
`Plugins/Convai/Config/ConvaiEditorSettings.ini`
In that file, find the following setting:
```auto
[ConvaiEditor]
editorUI.enabled=true
```
Change `editorUI.enabled=true` to `editorUI.enabled=false`.
Then open Unreal Engine.
Go to **Project Settings \> Convai** and add your API key. You should then be able to continue using it this way.

This issue occurs in version 5.6 and earlier. It is related to the Chromium version used by Unreal Engine. We are currently looking for a solution. If you want you can use 5.7.
