Addressables + WebGL not working.

Unity Engine
,
1

Hello,

Unity 2019.4.9f1
Addressables 1.16.1

In Editor with “Use Exiting Build” mod working
Android build also working with same setting.

On WebGL Build I get this error in Browser Console :

Exception encountered in operation CompletedOperation, status=Failed, result=UnityEngine.ResourceManagement.ResourceProviders.SceneInstance : Exception of type ‘UnityEngine.AddressableAssets.InvalidKeyException’ was thrown., Key=[bd10751d9f8749e45bd567e9ed4d109d], Type=UnityEngine.ResourceManagement.ResourceProviders.SceneInstance (Filename: ./Runtime/Export/Debug/Debug.bindings.h Line: 35)

As I understand bundle is downloaded in browser and error thrown On Completed Event.
Also InvalidKeyException will be thrown in Editor too in this case but I see it only in WebGL build.

Key bd10751d9f8749e45bd567e9ed4d109d exists in Catalog json

I resolved the issue with following steps :

1 ) Added this lines to nginx server where my addressables resides
add_header ‘Access-Control-Allow-Origin’ ‘*’;
add_header ‘Access-Control-Allow-Methods’ ‘GET, POST, OPTIONS’;
2)Changed compression for addressables from LZMA to LZ4 (WebGL don’t support LZMA )
3)Move build from Unity Connect to my server.

For some reason game on unity connect service caused all problems with addressables.
I was looking in the wrong place the root of the problem and I wasted all day on it
