Hey Summer,
> I think that the set up is finish . However, I can login to Gluu , but when the page show errors when I access /identity/home
For clarification, you mean you can access the oxTrust/Identity interface but are shown errors in the logs or the oxTrust/Identity interface is showing errors when you try to login?
```

I've never seen this kind of error before. What I can infer from it is that your AWS ALB isn't properly configured. Can you share with us your ALB configuration? There should be some session persistence with the stateful application oxTrust.

```
Can you also share how you've configured the AWS ECS instances? Perhaps we can gather more information about your configuration.
