Hi all,

We have a working authentication flow using the default authentication server and an Okta application.  
When trying to use a custom server we keep getting an error from the Okta SDK:

> AuthSdkError: OAuth flow response state doesn’t match request state

The above error is presented in the login callback response ([myapp.mydomain.com/login/callback](http://myapp.mydomain.com/login/callback)).  
The default server does it correctly.  
We’re using the Angular SDK.

Any ideas?

Thanks,  
Gal

Hi @segevgal! What version of the Angular SDK are you using?
