What URL did you configure within Okta as the post_logout_redirect_uri? Is it exactly the value (note that this is case sensitive) https://devsxa-global-preview.com/identity/postexternallogout?ReturnUrl=/

3

yep, configured same and it is not working

4

And it has the trailing / as well? Can you share a screenshot of the app settings within the admin console, just so we can double check?
